I've noticed an X server crash with nouveau on a Geforce FX 5200.
(display freezes, no mouse pointer present, not responding keyboard, no
X-related process appears with "ps awux", only available access is via ssh from
another PC).

OS: GNU/Linux - Slackware 'current' (x86)
X: Xorg-server 1.4.2 / Mesa 7.0.3 (but no 3D program has been used)
kernel: 2.6.27.4

Is this a regression, or is your first attempt at using nouveau on this
machine? 

Also, is it reproducible? If so, using ssh to attach gdb remotely before the
crash would help get a better back-trace (gdb /usr/bin/Xorg `pidof Xorg` , then
"cont", and after the crash "bt"). If it's a regression, can you use git bisect
on the ddx to point to a suspect commit?

I don't know if it's a regression: it's the 1st time I noticed this error,
after using nouveau for about 20 hours.
I've used it before (with ~3rd Oct. and ~19th Oct.-git), but it crashed in a
few hours with "DMA queue hang", both of times, so I can't tell when did this
one start.

At the moment I don't know if it reproducible, either. As I said it's the first
time, and btw I've not used any graphic-intensive program (except for kde 4.1
as a desktop manager, no compiz, no 3D, no games).
But as soon as I can, after next crash, I will send a more complete gdb 
backtrace.
Thank you.

I don't know if I can be helpful (maybe no: if so, sorry!), but enabling
Option "ShadowFB"
in xorg.conf file I don't see any X crash / DMA queue hang (so when
acceleration is disabled this driver seems to be stable).

--- Comment #10 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
