Complete dmseg

Hi 
The system hanged when watching a movie via VLC on one screen 
I have a dual monitor setup: one 1920x1080 and one 768x1366 (rotated 90? left)
DM is Kde 4.6

kernel kept on working: I could log in through ssh and audio kept on playing

I don't know how to reproduce the bug, but it sometimes happen, alos
sometimes
the system fails to disable the video output when going to suspension and I
have to manually reboot, but this might be an unrelated bug


if you need more info please go ahead and ask
Thanks in advance

How reproducible is this?

It's not clear based just on the backtrace if we're spinning in kernel
land in
the ioctl or if that's just where we happened to be at the time.  Could you
use
strace to see what syscalls are being generated.  That will give an idea if 
it's spinning in the kernel or somewhere in userland:

sudo strace -p <pid of server process>

Thanks for the suggestion, but strace dumps a huge amount of data and the bug
is very random
Once it happened when watching a movie via VLC, another time when using the
videochat function of google plus through firefox 7
Bith cases happened after a couple of days of uptime (and suspension: I never
turn the pc off)

I've been able to reproduce the freeze
I have a full strace for that but it's ~500mb uncompressed so I guess
it's not
really the case to post it. Is tehere a specific part you'll need?

It's looping on DRM_NOUVEAU_GEM_CPU_PREP ioctl which is periodically
interrupted by SIGALRM signal. On the kernel side it's hanging on a fence in
__nouveau_fence_wait.

It's a typical symptom of GPU lockup.

To fix this, someone needs to figure out why GPU locked up and/or how to reset
the GPU.

If needed I have the strace dump which is ~19MB compressed text. I can attach
it here or make it availabale through one of my external servers

It's not enough. Sorry.

You need to find quick and reliable way to reproduce it, like running some 
rendercheck or piglit test.

--- Comment #12 from Ilia Mirkin <imirkin at alum.mit.edu> ---
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
