Turns out high CPU Usage and slow UI issue is unrelated, it was due to
CPU governor reset to powersave and always using min frequency.
But the issue with nouveau timeout and system lockup still stays I
guess. Unless it was triggered by low CPU frequency.

** Description changed:
After upgrading from 20.04 to 20.10 system is unusable anymore due to
GPU issues with nouveau. Same system worked fine on 20.04.
Switching to nvidia proprietary driver and Xorg fixes the issue.
Symptoms:
System starts just fine, but overall UI
Tried 5.9.1 mainline kernel and got the same issue. The only difference
is Wayland recovered much faster (under 1 min). I didn't wait after
recovery to see if system will lockup completely and rebooted with
proprietary driver. Attaching dmesg output.
