Dear Maintainer,

after waking up from sleep state S3, nouveau produces the following error:

[   77.785163] nouveau 0000:01:00.0: fifo: fault 01 [WRITE] at 0000000000068000
engine 03 [IFB] client 08 [HUB/HOST_CPU_NB] reason 02 [PTE] on channel 2

- disabling channel
[   77.785232] nouveau 0000:01:00.0: Xorg[1425]: channel 2 killed!

This in turn kills the X server including the whole session.

During normal boot, nouveau already produces another error:

[   33.908446] irq 27 handler nvkm_intr+0x0/0x240 [nouveau] enabled interrupts
[   33.908538] WARNING: CPU: 3 PID: 2320 at kernel/irq/handle.c:161
__handle_irq_event_percpu+0x193/0x1a0

Full dmesg log is attached.

The last known working kernel version was linux-image-6.1.0-11-amd64.

Please can you open an issue upstream at
<https://gitlab.freedesktop.org/drm/nouveau/-/issues>?  You will need
to create an account there first.  Do let us know the URL of the issue
you open, so we can keep track of it.

(We ask you to do this yourself because the upstream developers will
likely need to ask you more questions.)

Ben.
