Hi!

This one fails our testing.

https://lava.ciplatform.org/scheduler/job/1181715

[    0.493440] ThumbEE CPU extension supported.
[    0.493646] Registering SWP/SWPB emulation handler
[    0.515073] clk: Disabling unused clocks

login-action timed out after 119 seconds
end: 2.2.1 login-action (duration 00:01:59) [common]

https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/jobs/7610484202

Failure does not go away with retries.

Now... I believe I seen similar failures before, but those did go away with retries. I guess I'll need help of our Q/A team here.

Best regards,
Pavel

Hello Pavel,

All the failed retired jobs from this pipeline ran on the same qemu LAVA machine. I've rerun the same test jobs on different qemu machines and they have booted okay, e.g.
https://lava.ciplatform.org/scheduler/device_type/qemu?dt_dt_dt_search=&dt_dt_dt_length=100&dt_dt_length=100&dt_dt_search=6.10&dt_length=100&dt_search=6.10.6#dt_

So we could blame it on the qemu-cip-siemens-muc machine, however, it was quite happily booting 6.10.6-rc1 a few days ago:
https://lava.ciplatform.org/scheduler/job/1180857
6.10.6-rc2 was also okay:
https://lava.ciplatform.org/scheduler/job/1181017

So it's an intermittent issue, however I can't say it's with the kernel or the qemu machine, maybe not so helpful, sorry.

Kind regards, Chris

Hi Chris, Hi Pavel,

thanks for reporting!

As Chris pointed out that this might be related to our qemu instance in the CIP lab. We had a look and found the attached kernel splat. This seems not a guest but a host problem (which is Debian/6.1 based and not 6.10).

I think you can continue, ignore the test result for this 6.10 release for now.

We will investigate further. Let's see.

For completeness the kernel log of the host is attached. LAVA runs into a timeout and marks the job as failed.

Best regards,
Florian

Hi,

I fixed the issue on our side - the test succeeds [1].

Hi!

Aha, thanks a lot, things make sense now.

Thanks for the log. It seems something is seriously wrong with the machine, likely deadlock in ext4 or storage subsystems. If there are any suspect messages before this one, they may be useful.

Best regards,
Pavel
