Nouveau - Sep 2014 - [Bug 83897] New: GK106 (GeForce GTX 660): Frequent GPU lockups

https://bugs.freedesktop.org/show_bug.cgi?id=83897

          Priority: medium
            Bug ID: 83897
          Assignee: nouveau at lists.freedesktop.org
           Summary: GK106 (GeForce GTX 660): Frequent GPU lockups
        QA Contact: xorg-team at lists.x.org
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: freedesk.apriori at spamgourmet.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: Driver/nouveau
           Product: xorg

I?m getting frequent GPU lockups which always seem to occur when playing video
(either via mpv or via flash-plugin). Not sure how to tell whether this affects
the 2D driver or the mesa one. Please reassign as you see fit.

The bug manifests as one of the following:
1. X screen freezes, no response when switching VTs, only SysRq+REISUB works.
2. X screen freezes, VT switch works, system can be rebooted by userspace
tools.

The common denominator in the reported errors seems to be: ?nouveau E[  
PFIFO][0000:01:00.0]? with either ?write fault?, ?read fault?, which is then
followed by ?PGRAPH engine fault?.

I?ll follow-up with a few relevant log files.

My current setup runs on:
* Linux 3.16.2
* Xorg 1.16.0

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
There should be some fixes in 3.17-rc1 and later which affect GK106, especially
if you're not using blob firmware. [After these changes it appears that the
blob firmware is no longer necessary, BTW, in case you're using it.]

Ilia, thanks! So maybe this has been resolved already? While I?m at it I?ll
still attach some of my collected logs, though, just in case something
interesting/new might be in there.

grep nouveau *.log|grep -C 15 "fault"

Output for ?grep nouveau *.log|grep -C 15 "fault"? on a few collected
logs of
the freezes described above.

This is for various kernel versions, I?ll follow up a table with the relevant
uname output for each logfile.

If there?s anything interesting in there that needs more than 15 lines of
context, let me know.

?grep "Linux version" *.log?. Some of the logs are missing the version
message,
though, since hard crashes screw up the journal?s reboot stamp, it seems, and I
had to resort to using ?journalctl --since $TIME?.

Recent lock-up logs, on Linux 4.0.3 and 4.0.4

I tried running Nouveau on Linux 4 again for a while, but the driver still
locks up frequently. Here’s some of the recent logs in case it helps.
