Public bug reported:
The 5.11-series 20.04 HWE kernels are not usable on my laptop. They boot
up to graphical login. Then the screen goes black for a second every few
seconds. When i try to log in the machine seems to hang and the desktop
never appears...
The kern.log shows a lot of these errors:
"[drm:amdgpu_pci_remove [amdgpu]] *ERROR* Hotplug removal is not supported"
Many call traces appear as well, involving [amdgpu] and [ttm].
I have reverted to using the 5.8 kernels.
