I've been using my 9 year old machine without issues up to Fedora 32
with kernel 5.8. Some weeks ago I upgraded to kernel 5.9. After working
for a random duration, my Display becomes mostly frozen, showing
noticeable flickering and the mouse reacts extremely slowly if at all.
Ctrl+Alt+t still opens a terminal but typing is a pain.
ssh from a different computer is possible with acceptable reaction times.
Ctrl+Alt+Del logs out session. A reLogin is possible with normal
reaction times, but again, only for an unforeseeable time!
I upgraded to F33, but the issue persisted. Then I did a fresh F33
install, from scratch. Unfortunately the unpredictable freezes occur again.
During an unresponsive period,
- "top" command shows process "kworker/u32:2-events_unbound" has high
CPU usage.
- "echo l > /proc/sysrq-trigger" followed by "dmesg" shows the
following, which hints me to the nouveau module:

# lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT
430] (rev a1)
=> connected with dual-link DVI to a 4K Display (3840x2160 resolution)
Although less frequently, the same problem also appears on my (old)
laptop since upgrading to kernel 5.9 (running Manjaro with Kernel
5.9.11-3 and gaphics card: NVIDIA Corporation G96GLM [Quadro FX 770M] at
resolution 1920x1200).
Any ideas how I can (help to) solve this problem?
Arsène
