Title:
nvidia: Xorg hangs at 100% CPU when playing video: "fallen off the
bus"
Status in “nvidia-graphics-drivers” package in Ubuntu:
Confirmed
Bug description:
This is likely a dupe of bug #1001007, but apport-collect says it's
better to file a new bug, so here I go. If they are a dupe, it may
not be just video playing that causes it, or just 3D usage, but maybe
VDPAU or a combination thereof. I do use 3D compositing with KDM in
KDE 4.8.3, and I have VDPAU installed.
I have been running Kubuntu on this Dell XPS M1330 laptop with NVIDIA
8400M GS since 2008 with no problems. Suddenly, after upgrading from
11.10 Oneiric to 12.04 Precise, I am regularly experiencing X hanging
with 100% CPU. So far, every time it has happened, it's been while
watching YouTube videos in Flash in Firefox. It may be minutes,
hours, or days between crashes.
When it happens, sometimes the cursor is movable, and sometimes the
cursor disappears. The rest of the screen freezes, but sound
continues playing. I can SSH in and see X at 100% CPU. I cannot
change VTs. I can sometimes SAK+K several times to kill X and then
KDM and X will restart--other times I have to power off.
I just downgraded to 295.20 to see if the bug exists in this version--
I've read in some places that people find 295.20 to be stable. Note
that even though I am filing this bug and ran apport under 295.20, I
have experienced the bug in 295.40 and 295.49, the versions in precise
and precise-updates.
When the hang happens, I see this in dmesg every time:

Again, this never, ever happened in all these years until I "upgraded"
from Oneiric to Precise. Now my laptop is completely unreliable--or,
at least, I risk a hang and having to kill all processes whenever I
watch a video. Not much of an upgrade. :(
I don't know what to do now. If 295.20 is not stable, should I keep
downgrading? I assume I'll eventually run into a version that won't
install on Precise, whether due to kernel incompatibilities or other
issues. I don't think downgrading the entire system to Oneiric
(reinstalling, at that) is a good option, either, as I'll be stuck
with older versions of other software, including all of KDE.
Here are some other links that may be relevant:
Thread on nvnews that I think is this same bug:
http://www.nvnews.net/vbulletin/showthread.php?t=178362
Probably not the same bug, but perhaps related in that it may be a regression
in 295.33+. The performance regressions may be fixed, but this hang is not:

I will do whatever I can to help debug this. This is very
frustrating!
