dmesg from the affected computer
I am the project lead of the Adélie distribution, a new desktop distribution
based on musl libc. I'm trying to ensure stability on different sets of
hardware. Everything is going well, except for nouveau.
On my Tesla cards (NV92 and NV94), all seems well. However, my test NV94 card
just died, so I replaced it with an NV106:
07:00.0 VGA compatible controller: NVIDIA Corporation GK208 [GeForce GT 730]
(rev a1) (prog-if 00 [VGA controller])

Kernel driver in use: nouveau
This is a PNY card, PCI-e x8, in x16 slot (only free slot left) on an Intel
S5000XVN.
We were tracking this bug on our own bug tracker, as we originally thought it
could be due to musl or out-of-date packages. That was back in the kernel 4.4
days. It seems that it probably isn't, though, since no updates seem to have
helped.
I will now share what we have there.

Attempting to switch from Firefox playing a YouTube video in 1080p
(https://www.youtube.com/watch?v=pOlWbSUQASs) to TigerVNC Viewer (which was
minimised) using composited icon task manager in Plasma 5 (with live
thumbnails), the machine locked up:

Screen stuck with a picture. No input is accepted. Information must be
gathered over SSH.
After some debugging and writing all this down, my attempt to `pkill -9 X`
yielded ssh locking up for 15 seconds, then the screen showing "No signal" and
ssh responding again with the following additional messages:
[ 5250.030144] nouveau 0000:07:00.0: kwin_x11[2212]: failed to idle channel 7

TTYs no longer worked. Running `startx` from SSH brought up a new Plasma
session on X display :1. After restarting X11, TTYs work correctly again.
While scrolling through https://bugs.freedesktop.org/show_bug.cgi?id=92077 (in
the middle of comment 17), I noticed that while I still had mouse button 0 down
and was moving the cursor over Firefox's scroll bar, the scroll bar was no
longer moving and neither was the content of the page. The mouse was still
accepting input, but I could not switch to a TTY. Everything else was locked.
New messages in dmesg:
[ 7474.808501] nouveau 0000:07:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]
[ 7474.808514] nouveau 0000:07:00.0: fifo: runlist 0: scheduled for recovery
[ 7474.808523] nouveau 0000:07:00.0: fifo: channel 8: killed
[ 7474.808532] nouveau 0000:07:00.0: fifo: engine 0: scheduled for recovery
[ 7474.808632] nouveau 0000:07:00.0: plasmashell[3872]: channel 8 killed!
`pkill -9 X` was a very simple fix this time. It threw me back to "No signal"
on the monitor, but then when I ran `startx` again, I was immediately greeted
with my normal desktop. Now there is a Plasma session on X display :2. FWIW,
there aren't any other X servers running.
Software that is always running when this happens (I don't know if one of them
is the culprit):
pidgin-2.12.0-r0
konsole-17.08.2-r0
firefox-esr-52.3.0-r0
All the KDE Plasma components at 5.8.7.
tigervnc-1.8.0-r0
One time, Quaternion (0.0.5-r0) was open, but it happened the second time
without Quaternion open, so I doubt it is the cause.
It only seems to take about half an hour to make this happen under my current
workflow, so I think debugging may be easy. I just don't know what to do to
debug further.
Attached is entire dmesg, and Xorg.*.log. Sorry, I don't have debugfs enabled
here, so I can't grab VBIOS yet. I will do that if needed, but it will need a
reboot.
