[PATCH V4 17/17] drm/amd/pm: unified lock protections in amdgpu_dpm.c

Fri Apr 1 08:56:22 UTC 2022

Hi Arthur,

apart from blacklisting amdgpu I generally advise to SSH from another 
computer into the affected system if you have a problem like this.

Additionally to what Evan said I suggest that you enable 
CONFIG_LOCKDEP_SUPPORT in your kernel configuration. This will yield 
warnings in your system log in case of deadlocks or accidentally 
forgetting to unlock something.

Regards,
Christian.
