            Bug ID: 110996
           Summary: swaywm (wayland) crashes when turning off monitors
                    through dpms
           Product: xorg
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: sjon-bheiZbv1XdVtjaSKtHux1w@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

My wayland setup always crashes when powering my 2 DP monitors down through
dpms. Afterwards I can't get the monitors to power on (through ssh) - only fix
is a reboot.
This is a GTX 1080 Ti btw

[Bug 110996] swaywm (wayland) crashes when turning off monitors through dpms

--- Comment #1 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
What was the first group of errors before the first "core notifier timeout"?
That should help inform why there was a gpu hang. Actually, can you reproduce
when booted with

drm.debug=0x14 nouveau.debug=disp=trace

and then reproducing this issue. Only the first few sets of errors are
interesting (really the first, usually), everything after that is just
follow-on fail.

Looks like there are two bugs here, BTW:

1. We hang the EVO engine somehow
2. We have some kind of page map fail with evo_wait (hence the BUG at the end)

Created attachment 144636
  --> https://bugs.freedesktop.org/attachment.cgi?id=144636&action=edit
filtered kernel messages with drm.debug=0x14 nouveau.debug=disp=trace

I'm not sure what caused the 'core notifier timeout' messages to start - but
there was at least half an hour between that error and the actual crash. I'll
attach the requested log - it's huge and doesn't show the same hang. The
problem did occur, my monitors turned off and my machine needed a reboot
