Hi Vincent,

Please see the bisection report below about a boot failure on rk3328-rock64 with the pwmg/integ branch.

Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org but this one looks valid.

There's nothing in the serial console log, probably because it's crashing too early during boot.

Some details can be found here:

https://kernelci.org/test/case/id/5ffb978de38e717501c94cd8/

The bisection was run with CONFIG_RANDOMIZE_BASE=y enabled, but the same issue occurs with a plain defconfig from that branch. Results with other configs and platforms can be compared here:

https://kernelci.org/test/job/pmwg/branch/integ/kernel/v5.11-rc3-13-gcea05edf93998/plan/baseline/

Please let us know if you need some help to test a fix or debug the issue.

Thanks,
Guillaume

Hi Vincent,

Please see the bisection report below about a boot failure on rk3328-rock64 with the pwmg/integ branch.

Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org but this one looks valid.

There's nothing in the serial console log, probably because it's crashing too early during boot.

Some details can be found here:

https://kernelci.org/test/case/id/5ffb978de38e717501c94cd8/

The bisection was run with CONFIG_RANDOMIZE_BASE=y enabled, but the same issue occurs with a plain defconfig from that branch. Results with other configs and platforms can be compared here:

arm64/hikey: update defconfig

Signed-off-by Vincent Guittot <[email protected]>

Hi all,

Regardless of this bisected issue, such commit and its description is not good. Multiple entries are added and removed - no clue why. Was it savedefconfig? Maybe yes, maybe no, who knows... If yes, it should be reverted because savedefconfig is known to remove important features *later* (vide DEBUG_FS in the past).

Instead, commit should explicitly explain for each item why this is added or removed.

Best regards,
Krzysztof

Hi Vincent,

Please see the bisection report below about a boot failure on rk3328-rock64 with the pwmg/integ branch.

Reports aren't automatically sent to the public while we're trialing new bisection features on kernelci.org but this one looks valid.

Thanks for the report. I'm going to have a deeper look.

The culprit patch is there to set defconfig for running some of our tests on hikey and hikey960 boards and doesn't aim to be merged upstream.
It sets some scheduler features: disable auto group because I run tests related to cgroups and scheduler. But those are generics It enables default trace events which are generic too And It enables some hikey specific config.
TBH I don't see any straightforward relation with rockchip. As a 1st guess I would say that it is related to trace events.

Quoted 8 lines

There's nothing in the serial console log, probably because it's crashing too early during boot.

Some details can be found here:

https://kernelci.org/test/case/id/5ffb978de38e717501c94cd8/

Quoted 8 lines

The bisection was run with CONFIG_RANDOMIZE_BASE=y enabled, but the same issue occurs with a plain defconfig from that branch. Results with other configs and platforms can be compared here:

https://kernelci.org/test/job/pmwg/branch/integ/kernel/v5.11-rc3-13-gcea05edf93998/plan/baseline/

Please let us know if you need some help to test a fix or debug the issue.

I don't have any rockchip board on which I can run tests but I can push an updated version of the patch without trace events if this can then be then tested on kernelci rockchip board.

Regards,
Vincent

Some details can be found here:

https://kernelci.org/test/case/id/5ffb978de38e717501c94cd8/

The bisection was run with CONFIG_RANDOMIZE_BASE=y enabled, but the same issue occurs with a plain defconfig from that branch. Results with other configs and platforms can be compared here:

Please let us know if you need some help to test a fix or debug the issue.

I don't have any rockchip board on which I can run tests but I can push an updated version of the patch without trace events if this can then be then tested on kernelci rockchip board.

It's odd that there is no output from the kernel at all, which rules out most of the options that change, as they should only have an effect later during boot.

One thing I noticed is that the last successful boot has a kernel image size just under 32MB for the vmlinux, while the failing configurations have more than 34MB.

I looked at the loadaddress as well:

11:43:57.119234  Filename '536723/tftp-deploy-j462agcw/kernel/Image'.
11:43:57.122622  Load address: 0x2000000
11:43:59.708404  Bytes transferred = 34361856 (20c5200 hex)

...
11:43:59.814346 Filename '536723/tftp-deploy-j462agcw/ramdisk/ramdisk.cpio.gz.uboot'. 11:43:59.814638 Load address: 0x4000000 11:44:00.447924 Bytes transferred = 8517374 (81f6fe hex)

So the ramdisk and the kernel overlap when the kernel is larger than 32MB!

Good catch Arnd.
Thanks
