Package: src:linux
Version: 6.9.9-1
Severity: minor

Dear Maintainer,

I just faced this boot problem on my sid system for the first time
since I updated the Linux kernel a few days ago.

I do not know if it could be something related to some hardware failure
or a possible software bug in the linux kernel or a service.

Regards,
Patrice

I just faced this boot problem on my sid system for the first time
since I updated the Linux kernel a few days ago.
Could you please provide an unfiltered kernel log? The one you attached
does not even contain the full crash message. Nor is it the first crash
(visible by the D in the taint string).

Regards,
Bastian

Hi Bastian,
Sorry I probably did something wrong with gnome-logs. Let's go then
with journalctl
and here are attached the complete log files, or at least I hope so!
Thanks,
Patrice

Then later on the kernel heap allocation crashes, suggesting memory
corruption. Maybe related to the first failure, maybe not.

- There is a newer kernel version available in unstable now (6.10.6 or
maybe 6.10.7 by the time you read this). Does that fix the issue?

- Do these same error messages appear on every boot?

- If you prevent the dell_wmi_sysman module loading, by adding
"blacklist=dell_wmi_sysman" to the kernel command line, do all of the
error messages stop appearing?

Often, but not always. I was also not sure if it could be related to #1076561
that I had seen pass by at the same time.

Would you like me to reinstall one of those kernel versions so as to

and try adding the option?

That's good news! But 6.11 will not reach unstable for a few weeks.

Hi Ben,

All my attempts both after installing 6.9.9 on my current Sid system,
or using a snapshot of Sid at that time when linux-image-6.9.9 was pushed
(fastidious by the way) have failed. I am not able to get the issue again.

But since then it occurs to me that there was also a firmware update (fwupd)
for my Dell laptop system (1.32.0 to 1.34.0)
