--- Comment #2 from Michał Pecio (michal.pecio@gmail.com) ---
6.12 to 6.18 is a fairly large spread, and it isn't even clear if the bug is a
regression or perhaps some CachyOS vs Arch difference. And the GPU uses an out
of tree driver, hmm.

IDK about CachyOS, but Arch package archive has 'linux' (non -lts) packages for
all major versions from 6.12 to 6.18. Could you start with testing these to
find which release broke things? And try to use the same NVIDIA driver each
time, or (preferably) see if the problem occurs with Nouveau.

I would wager that resets are deliberate (HID driver seems to do that in
response to USB errors), but that still doesn't explain why USB errors occur
due to GPU activity and why some kernels work but others don't.
