Hi, this is your Linux kernel regression tracker.

Thx for your report. I'm not one of the developers for this area of the
kernel, but to my untrained eyes it looks like this patch might fix your
problem:

https://lore.kernel.org/all/20221219104718.21677-1-christian.koenig@amd.com/

Anyway, to be sure the issue doesn't fall through the cracks unnoticed,
I'm adding it to regzbot, my Linux kernel regression tracking bot:

#regzbot ^introduced aab9cf7b695413
#regzbot title drm: amdgpu: use-after-free and random computer hangs
#regzbot monitor:
https://lore.kernel.org/all/20221219104718.21677-1-christian.koenig@amd.com/
#regzbot fix: drm/amdgpu: grab extra fence reference for
drm_sched_job_add_dependency
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
