Bug Description
After some update my display randomly goes black for just a second and comes back. It happens randomly and I looked into journalctl and found this error message.

Thanks for the bug report. CurrentDmesg.txt appears to show the amdgpu kernel driver crashed in display-related functions, so that is almost certainly the problem here.
Given how new the hardware is, I would recommend installing Ubuntu 24.04 instead, which includes a newer kernel and newer graphics drivers.
