Hey Gerd, Thomas,
I've got the following oops that looks bochs-drm related on the current
HEAD ( 4800575d8c0b2f354ab05ab1c4749e45e213bf73 ) and it's been there for at least a few days; this is

under qemu with:
qemu-system-x86_64 -M q35 -nographic -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2

qemu version: qemu-kvm-9.1.2-2.fc41.x86_64 (i.e. Fedora41 build)

I've tried reverting:
4a30d193f0ef7a8c2f6eef4b8b18a498e99db34b (HEAD) Revert "drm/bochs: use devm_ioremap_wc() to map framebuffer" 082362340422eaff688f0d83ecbe71172c033f51 Revert "drm/fbdev-shmem: Remove obsolete setup function" f814356c3a2f0cc549fcc5ed4b36ec5ac6591cb3 Revert "drm/bochs: Run DRM default client setup" 0e64fa12581e8653d45ed43769b26f4f80a621bb Revert "drm/bochs: Return error from correct pointer" 1ab79b4c32d13559c6dfe6c721794546414456a9 Revert "drm/bochs: Use video aperture helpers" f822c9f07028c5de45a0bae38f0087696bc1f4cb Revert "drm: Remove DRM aperture helpers"

but that's not helped so far

If I remove -nographic and enable the normal console (console=tty0 console=ttyS0 ) it still happens.

The oops has :

[   78.463760][    T1]  bochs_pci_driver_init+0x8a/0xc0

in it, hence why I'm blaming that.
(Other odd observation, the Tuxen flicker heavily during booting!)

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged without removing it. Hence clear the respective call to drm_dev_put() from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error message is shown below:

After unplugging the DRM device, clients will close their references. Closing the final reference will also release the DRM device.

Thanks for reporting. I've been able to reproduce the problem by setting CONFIG_DEBUG_TEST_DRIVER_REMOVE <https://elixir.bootlin.com/linux/v6.13-rc2/K/ident/CONFIG_DEBUG_TEST_DRIVER_REMOVE>=y.

Ah OK, so fairly obscure (I'm running something close to a all-yes-config because I'm mostly build testing obscure stuff).

Quoted 2 lines

The attached patch fixes the problem for me. Could you please test and report back the results.

That gets me a different oops; this was run with:
qemu-system-x86_64 -M pc -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=tty0 console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2

It looks to me if it made the mistake of trying to print something in the middle of being removed:

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

Hey Gerd, Thomas,
I've got the following oops that looks bochs-drm related on the current

The oops has :

in it, hence why I'm blaming that.
(Other odd observation, the Tuxen flicker heavily during booting!)

The config is a fairly full yes-config ish; see attached.
Thanks for reporting. I've been able to reproduce the problem by setting CONFIG_DEBUG_TEST_DRIVER_REMOVE <https://elixir.bootlin.com/linux/v6.13-rc2/K/ident/CONFIG_DEBUG_TEST_DRIVER_REMOVE>=y.
Ah OK, so fairly obscure (I'm running something close to a all-yes-config because I'm mostly build testing obscure stuff).

Yeah, it's the first time I saw this option. But as we usually don't unload the bochs driver, we'd otherwise not found the issue.

The attached patch fixes the problem for me. Could you please test and report back the results.

It looks to me if it made the mistake of trying to print something in the middle of being removed:

That is also graphics, but looks like something unrelated to bochs. It's probably been there for a while already. I didn't see this in my test, but I'll try to reproduce. I assume your test system starts up in VGA text mode first?

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

Hey Gerd, Thomas,
I've got the following oops that looks bochs-drm related on the current

The oops has :

in it, hence why I'm blaming that.
(Other odd observation, the Tuxen flicker heavily during booting!)

The config is a fairly full yes-config ish; see attached.
Thanks for reporting. I've been able to reproduce the problem by setting CONFIG_DEBUG_TEST_DRIVER_REMOVE <https://elixir.bootlin.com/linux/v6.13-rc2/K/ident/CONFIG_DEBUG_TEST_DRIVER_REMOVE>=y.
Ah OK, so fairly obscure (I'm running something close to a all-yes-config because I'm mostly build testing obscure stuff).

Yeah, it's the first time I saw this option. But as we usually don't unload the bochs driver, we'd otherwise not found the issue.

The attached patch fixes the problem for me. Could you please test and report back the results.

It looks to me if it made the mistake of trying to print something in the middle of being removed:

That is also graphics, but looks like something unrelated to bochs. It's probably been there for a while already. I didn't see this in my test, but I'll try to reproduce. I assume your test system starts up in VGA text mode first?

Yes; I can try a bisect a bit later; your fix seems to have fixed it if I boot with console=ttyS0 and -nographic on qemu, which gets me back to booting OK
on serial which is what I normally do. This hide_cursor case is only
with video/console which I don't run very often on this build, so I'll guess a bit where to start my bisect.

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

That gets me a different oops; this was run with:
qemu-system-x86_64 -M pc -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=tty0 console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2
It looks to me if it made the mistake of trying to print something in the middle of being removed:

From the stack trace below, I'd say it is the one at [1]. But I fail to reproduce the problem.

Could you please send me the complete output of dmesg after the system finished booting?

Best regards

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

Sure; this is as far as it gets until it hits the vga oops that stops it:

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

The attached patch fixes the problem for me. Could you please test and report back the results.
That gets me a different oops; this was run with:
qemu-system-x86_64 -M pc -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=tty0 console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2
It looks to me if it made the mistake of trying to print something in the middle of being removed:

From the stack trace below, I'd say it is the one at [1]. But I fail to reproduce the problem.
Could you please send me the complete output of dmesg after the system finished booting?
Sure; this is as far as it gets until it hits the vga oops that stops it:

OK, this one is older; I can reproduce it on 6.12; I'll chase it further.

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

The attached patch fixes the problem for me. Could you please test and report back the results.
That gets me a different oops; this was run with:
qemu-system-x86_64 -M pc -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=tty0 console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2
It looks to me if it made the mistake of trying to print something in the middle of being removed:

From the stack trace below, I'd say it is the one at [1]. But I fail to reproduce the problem.
Could you please send me the complete output of dmesg after the system finished booting?
Sure; this is as far as it gets until it hits the vga oops that stops it:

I'm back to 6.9.0 and it's still there, I'll keep going.

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

The attached patch fixes the problem for me. Could you please test and report back the results.
That gets me a different oops; this was run with:
qemu-system-x86_64 -M pc -cpu host --enable-kvm -smp 4 -m 2G -kernel /discs/fast/kernel/arch/x86/boot/bzImage -append "console=tty0 console=ttyS0 root=/dev/vdb1 single" -drive if=virtio,file=/discs/more/images/debian12-64scan.qcow2
It looks to me if it made the mistake of trying to print something in the middle of being removed:
From the stack trace below, I'd say it is the one at [1]. But I fail to reproduce the problem.

Could you please send me the complete output of dmesg after the system finished booting?
Sure; this is as far as it gets until it hits the vga oops that stops it:
I'm back to 6.9.0 and it's still there, I'll keep going.

I'm back to 6.3.0 and it's still there; I tried building 6.0 but it doesn't want to build on modern compilers without a fight.

So hmm.

Subject: [PATCH] drm/bochs: Do not put DRM device in PCI remove callback

Removing the bochs PCI device should mark the DRM device as unplugged
without removing it. Hence clear the respective call to drm_dev_put()
from bochs_pci_remove().

Fixes a double unref in devm_drm_dev_init_release(). An example error
message is shown below:

After unplugging the DRM device, clients will close their references.
Closing the final reference will also release the DRM device.

The attached patch fixes the problem for me. Could you please test and report back the results.
That gets me a different oops; this was run with:

It looks to me if it made the mistake of trying to print something in the middle of being removed:
From the stack trace below, I'd say it is the one at [1]. But I fail to
reproduce the problem.
Could you please send me the complete output of dmesg after the system finished booting?
Sure; this is as far as it gets until it hits the vga oops that stops it:

I was able to reproduce it a single time. My setup is

- CONFIG_DEBUG_TEST_DRIVER_REMOVE=y
- CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER=y
- startup with vgacon
- 'quiet' on kernel command line (important!)

and then I got the segfault you report.

With the provided stack trace and log, I think I got some idea what is happened

[   79.802400][    T1] BUG: kernel NULL pointer dereference, address: 000000000000020c

I've not been able to figure out what is a offset 0x20c (524 decimal). None of the structs involved appears to have any fields starting at this offset. The nearest case is vc_hi_font_mask, [2] which is at +520. Could be related to aligned memory access. get_color() would read that field. [3] vc_num at +512 is another candidate.

The attached patch fixes the problem for me. Could you please test and report back the results.
That gets me a different oops; this was run with:

It looks to me if it made the mistake of trying to print something in the middle of being removed:
From the stack trace below, I'd say it is the one at [1]. But I fail to
reproduce the problem.
Could you please send me the complete output of dmesg after the system finished booting?
Sure; this is as far as it gets until it hits the vga oops that stops it:
I was able to reproduce it a single time. My setup is
- CONFIG_DEBUG_TEST_DRIVER_REMOVE=y
- CONFIG_FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER=y
- startup with vgacon
- 'quiet' on kernel command line (important!)
and then I got the segfault you report.
With the provided stack trace and log, I think I got some idea what is happened

[   74.177273][    T1] bochs-drm 0000:00:02.0: vgaarb: deactivate vga console
This comes from the first iteration in really_probe() [1]. This is the bochs instance that will be removed. It should install fbcon, but that gets deferred.

I don't think that's correct, because ...

[   74.265882][    T1] fbcon: Remapping primary device, fb1, to tty 1-63

... the above line I think is only ever printed if we're not deferred anymore:
- One such printk is in fbcon_remap_all(), but after checking for deferred_takeover and bailing out if that's set.
- The other is in do_fb_registered -> fbcon_select_primary (but only if CONFIG_FRAMEBUFFER_DETECT_PRIMARY is set), which is before we check for deferred_takeover. But if deferred_takeover is set that path should print

  		pr_info("fbcon: Deferring console take-over\n");

which does not seem to be the case.

But then I have no idea why deferred fbcon could have any impact at all. Really puzzling.

[   79.802400][    T1] BUG: kernel NULL pointer dereference, address: 000000000000020c
I've not been able to figure out what is a offset 0x20c (524 decimal). None of the structs involved appears to have any fields starting at this offset. The nearest case is vc_hi_font_mask, [2] which is at +520. Could be related to aligned memory access. get_color() would read that field. [3] vc_num at +512 is another candidate.
