    drm/nouveau: Fix sleep while atomic in nouveau_bo_fence().


i can't change output resolution for fbcon. It always come up with
1280x1024x32
initial size, but then X succesfully  use it's part of VRAM. But fbcon
buffer
currently marked as pinned in VRAM, so on low-vram card like 16Mb TNT2 I run
out of memory too fast.

Logs will follow, kernel command line as shown by cat /proc/cmdline:

BOOT_IMAGE=2.6.36-nuvo ro root=1601 nocd nopcmcia max_loop=255 nohotplug
vt.default_utf8=0 video=VGA-1:800x600-16 at 85

Hm, a bit more informative lines can be helpful here ... for example, color
depth and/or vertical refresh rates .....

I have fbcon, nouveau, drm  compiled as modules, and my system starts up with
old VGA text mode, then  during udev startup  nouveau module will be
auto-loaded.

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
