> Description:
X server slowly dies, with screen content no longer being updated.

The X driver is the built-in "modesetting" one.

[ 214164.183262] Asynchronous wait on fence i915drmkms0:X[4015]:50f30e timed out \
(hint:0xffffffff80742b40) [ 214165.923258] i915drmkms0: notice: Resetting rcs0 for \
preemption time out [ 214165.923258] i915drmkms0: notice: firefox91[19431] context \
reset due to GPU
> How-To-Repeat:

> Fix:
Killing the X server, switching to a text console, then restarting X
resolves the problem.
