Nouveau trouble

[Anders Wegge Keller]

 With a Dell Precision M4600, running Fedora 21, I've started experiencing
troubles with my X sessions within the last six months. The symptoms is that
X frezzes, and sometimes, but not always, I can switch to a VT and make a
controlled shutdown. At other times, the machine is totally unresponsive,
and the only resort is to force a powerdown. I cannot state a more precise
date for the first occurrence, as I wrote it off as thermal problems.
However, after a vacuum session, the problem persisted, so I dug into the
system logs. In /var/log/messages, I find the following pattern on each
occurrence:

Apr 28 00:18:35 localhost kernel: [11057.344140] nouveau
E[gnome-shell[2031]] multiple instances of buffer 156 on validation list

...

The graphics card identifies as follows:

01:00.0 VGA compatible controller: NVIDIA Corporation GF108GLM [Quadro
1000M] (rev a1)

The frequency of the lock-ups are independant on wheter Optimus Prime is
enabled or not.

Has anyone seen something similar to this before, and if so, what cures have
you found?

 After a week with 2.4.59, and no errors, I upgraded t 2.4.60 again. After a
few hours I had the same symptoms, so there's definitely an indication of a
problem with the 2.4.60 release.

If you're on the F22 beta, or can be, take a look at 
https://admin.fedoraproject.org/updates/libdrm-2.4.61-3.fc22

This fixes the problem for me.

 So far, it looks like downgrading to libdrm-2.4.59 has fixed the problems.
I haven't seen X lock up until now.

 I have installed the previous version of libdrm, and will try to see if I
can reproduce it, after the next reboot. As an added information, I've found
that using the channel popup-menus in X-Chat is a pretty surefire way of
provoking the fault, so it should be easy enough to see if the behaviour
changes.

I just ran into this with Fedora 22, and was pointed to a libdrm 2.4.60
bug. If you downgrade to libdrm-2.4.59 (perhaps this build
http://koji.fedoraproject.org/koji/buildinfo?buildID=606048), can you
reproduce?
