Hi. I have been experiencing random system freezes. It happens seldom, once every few days.
Hardware is TUXEDO InfinityBook Pro AMD Gen9

Looking into /var/log messages I see this just before system becomes unresponsive:

According to post on Arch I should use kernel parameter `amdgpu.dcdebugmask=0x10`

This is the post:
https://bbs.archlinux.org/viewtopic.php?id=302499

Since I neither understand if my issue is caused by the GPU or ACPI (or something else) nor what this kernel parameter does, I'm hesitating to try it (also hard to test as this issue happens rarely).

Please do tell if some more debugging info would help, or how I could debug this further.
