Why does keyctl.c declare it as 'asmlinkage'?

Because it's wrong.

Am chasing another issue - once I got past that, it wouldn't boot at all. Grub would act like it was loading, then 2 seconds or so later, grub would start up again. My first guess was CONFIG_DEBUG_RODATA=y, but I ruled that out. More detail once I've done some more binary searching and ruled out self-inflicted idiocy....

Rebuilt from a completely new and clean tree, 2.6.14-mm1 is fine, 2.6.15-rc1 will start booting OK, -rc1-mm1 chokes up almost instantly. It doesn't live long enough for either/both earlyprintk=vga or initcall_debug to output anything - grub says "loading", clears the screen, and 2 seconds later the laptop gives the 'ka-chunk' noise it does on a system reset, and I'm looking at the BIOS splash screen.

Any obvious places to look, or time to play bisection on the 600 patches in -mm?

Can't think of anything, sorry. The obvious area to probe is around the x86 and mm patch subserieses.

Hi

Hi,

This has been one of the best -mm releases in a while. No problems compiling or running - and so far nearly 18 hours uptime without any surprises.

Following up on a posting from the last -mm release, I'm still seeing errors loading multiple network drivers as modules (e100 and sky2) when CONFIG_PREEMPT_BKL is enabled, with 2.6.14-mm1, 2.6.14-mm2 and now 2.6.15-rc1-mm1. Mainline git doesn't exhibit the problem, so it's -mm specific.

This is what is logged:

Nov 18 17:40:42 tornado kernel: e100: 0000:06:03.0: e100_eeprom_load: EEPROM

Nov 18 17:40:42 tornado kernel: ACPI: PCI interrupt for device 0000:06:03.0

disabled
Nov 18 17:40:43 tornado kernel: sky2: probe of 0000:04:00.0 failed with error -95

I'm certain that both of these NIC's are OK as they work fine with CONFIG_PREEMPT_BKL not selected.

With CONFIG_PREEMPT_BKL disabled and an otherwise identical config, the driver modules load up just fine.

A known good kernel with this config was 2.6.14-rc5-mm1.
I have backed out git-netdev-all but it made no difference, as well as backed out the e100 changes in -mm on 2.6.15-mm2, again no difference. So I suspect it's not a netdev driver problem.

What else can I do to help narrow down the problem? What other trees or patches would be worth backing out to try and narrow it down?

.config and system details are up on http://www.reub.net/kernel/

We'll have to try harder. -mm2 is up there now, to break everything again.

I'd be suspecting the PCI changes firstly. That's gregkh-pci-*.

Conceivably git-acpi, but that hasn't changed in quite some time. In fact, no ACPI changes since 2.6.14-rc5-mm1.

After that I don't know, sorry. Binary search time?

Andrew Morton wrote (ao):

I second this. It is stable under (my) load where the 2.6.14-mm releases crashed. Most likely due to Reiser4, but couldn't capture anything yet (netconsole troubles, have to investigate more) so not sure.

Reiser4 is very slow though, as is discussed on the reiserfs list atm.

Nice :-)

Still looking into this one. It appears that backing out the gregkh-pci patches in -rc1-mm2 made no difference.

I don't think I should be able to make this happen so easily though:

Looks like 2.6.15-rc1-mm1 has total crap in ptrace_get_task_struct (and it looks like my fault because I sent out a wrong patch).

The patch below should fix it:

Hi,

Any ideas why the mousedev module does not load automaticly with 15-rc1-mm1?

With 14-rc4-mm1 all is ok. With 15-rc1-mm1 I have no /dev/input which causes Xorg fun. The mouse is connected to a usb hub and is detected when I unplug and replug it. I used make oldconfig from a 14-rc4-mm1 config. Dist is debian amd64 unstable and is up to date.

When I manually modprobe mousedev things work as expected

DRM works fine and dri is enabled.

Ideas,
Ed Tomlinson

Are you using debian?
If so, what version of udev are you using? There are some known reported problems with this, so I would suggest referring to the udev bug list.

If you aren't using Debian, please let us know. Also, what version of udev are you using?

thanks,

greg k-h

In particular check the version requirements for udev - you need to be on a version greater than or equal to 71. Sarge/stable has a really old version. In particular I am running unstable as I had too many funny errors (including this one) - but etch should be fine.

If running another distribution check this also as it is a real requirement.

To find the latest version of udev required check Documentation/Changes

Interestingly the same udev works fine with 14-rc4-mm1. I'll check the debian bugs.

Lots of things have changed in the input core since that kernel version. Others have reported this same issue, see the thread from Ted Tso on lkml a while ago when 2.6.15-rc1 came out.

thanks,

greg k-h

There does not seem to be anything that fits this reported as a debian bug. Where is the udev bugs list?

TIA
Ed Tomlinson

For Debian? I have no idea as I do not use it :)

For general udev issues/queries try the linux-hotplug-devel mailing list.

Oh, and are you sure you actually have the proper module loaded?

thanks,

greg k-h

Think only the mousedev module is not loaded. Once I modprobe it the mouse works and the /dev/input/mice appears. The mouse works normally with all buttons and wheels acting normal.

Ed

I was having this on one of my machines. I'll try and track this down next week probably if it still occurs and use git-bisect on it if nobody else does first though. I'll check out the thread mentioned as well.

Then you just need to make sure that module is loaded properly, which doesn't sound like a udev issue :)

thanks,

greg k-h

My personal experience was that all my modules loaded automatically, including mousedev and then mousedev doesn't anymore (but haven't checked very latest kernel tree) and then you have to manually load.

Then its a kernel problem.

It works with the _same_ user space in 2.6.14-rc4-mm1 and fails with 15-rc1-mm2... This implies either something is broken in the kernel or udev is not doing its job with the new (input?) changes. Since I switched to udev this summer I have not had to load many modules certainly not mousedev.

I'll do a bit of experimenting this weekend to see if I cannot figure out more about what is happening.

Thanks for the help
Ed

I would suggest using git-bisect to find the problem - I do know that the problem was/is in Linus Torvalds tree. It was fine around 2.6.13 timeframe and broke sometime after this. I find git-bisect very powerful for testing these types of bugs.

I was going to test myself in this way but the machine which experienced the problem caught fire!! I know this sounds like the dog ate my homework but unfortunately it was true and it was a machine I borrowed too....

Or a broken userspace configuration that just happened to work previously :)

I really don't know which one this is, but as it seems it only is showing up on Debian systems...

thanks,

greg k-h

OK. Have got quite a bit further in tracking this down and will now log with Debian somehow.

It is definitely userspace but I don't know enough about that to say whether it is udev (Debian rules) or something else.

I used git-bisect with 2.6.14 and 2.6.15-rc1 as start and end points. In the end the patch which caused it to break was the final one - just altering the Makefile with the version number. I've reverified as well by going back to 2.6.15-rc1 and just altering it to 2.6.14 and the problem (mousedev not loaded automatically and no /dev/input /mice) disappears. I almost thought I'd made a mistake in my testing until I manually altered that makefile!!

It is definitely not a kernel issue in my opinion.
