           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

Kernel log from bootup to crash

I have a completely reproducible hang in the nouveau kernel module.  It hap=
pens
when I've run a vdpau or OpenGL video session and then exit it, under the K=
DE5
desktop.  It doesn't happen under KDE4, with the same binaries and librarie=
s.

I start the MythTV frontend (fullscreen) or xine (windowed) from within KDE=
5.=20
Playback is normal, everything works properly, until I attempt to exit
playback.  At that moment, the screen locks up.  The keyboard becomes
non-responsive, the mouse cursor still moves, my desktop clocks stop updati=
ng,
and I have to ssh into the machine to reboot it.

I'm attaching the Xorg and dmesg logs.  The end of the dmesg log includes s=
ome
lines from the kernel log, retrieved after the reboot.  The relevant lines =
are:

kernel: nouveau 0000:01:00.0: msvld: intr 00000002
kernel: nouveau 0000:01:00.0: mythfrontend[2971]: failed to idle channel 19
[mythfrontend[2971]]
kernel: nouveau 0000:01:00.0: mythfrontend[2971]: failed to idle channel 19
[mythfrontend[2971]]
kernel: nouveau 0000:01:00.0: fifo: runlist update timeout
kernel: nouveau 0000:01:00.0: fifo: INTR 00000001: 0000000b

The Mesa/DRI libraries are at version 17.3.3, but this happened with earlier
versions as well.  My kernel is kernel.org 4.14.12 with no additional patch=
es.

The xf86-video-nouveau component is at tag xf86-video-nouveau-1.0.15
The xserver component is at tag xorg-server-1.19.5
