Hi all,

This is an error is the syslog found after investigating a Youtube FF chirping hang
while running kseftest of 6.3-rc6 torvalds tree kernel.

Running multimedia and kselftest might seem off, but multimedia performance on Linux
and open source software is a very interesting research area.

Here is the trace from the log:

Hope this helps.

The platform is Ubuntu 22.10 kinetic kudu on Lenovo IdeaPad 3 15ITL6,
the above mentioned 6.3-rc6 torvalds tree kernel and GGCN51WW original
Lenovo BIOS.

Please find the config and the lshw output and this listing at the URL:

I will add "make kselftest" log to the directory with lshw and config.

Best regards,

Thanks for the report!
The kernel stack there is not a real kernel crash, but is a result of a WARN_ON() in the code.
However, there's a kernel NULL pointer deref later. Can I ask you to collect a log of the
crash itself? Maybe with netconsole if the machine completely crashes?

Hi, Mr. Greenman,

Did you see the provided journalctl at the link?

I have found this interesting information:

                                                other info that might help us debug this:

Other than this, I am not technically savvy enough to give the other possible logs
than /var/log/syslog and journalctl ...

Could you please give additional instructions.

Thank you very much.

Hi, Gregory,

I have browsed through the material I provided, and somehow the NULL pointer dereference is not
there in the logs. But I am certain that I have copied this line with the kernel BUG from the
logs. I haven't erased any logs yet, so I believe I will be able to recover these log lines
as soon as I get physically to the device.

Best regards,
Mirsad
