system log from crash

Description of problem:

This seems kind of weird, but I can reliably trigger a hang of the GUI on my system by running geeqie and right-clicking on the file list. The context menu comes up, but the mouse and keyboard immediately become nonresponsive. I can ssh in and reboot, though.


Version-Release number of selected component (if applicable):

xorg-x11-drv-nouveau-1.0.11-2.fc22.x86_64

How reproducible:

Seems to be always.

Steps to Reproduce:
1. run geeqie in a directory with a number of jpg files
2. right click on one of those files in the list
3. boom

Actual results:

mouse and keyboard freeze

Expected results:

not that.

Additional info:

system log is full of lines like:

Apr 24 21:26:22 system.example.org kernel: nouveau E[   PFIFO][0000:01:00.0] PBDMA0: ch 1 [DRM] subc 0 mthd 0x001c data 0x00001004

And by "full", I mean about 7.6 million lines of that in a few minutes -- so much that it seems to have wiped out previous log information by sheer volume, triggering systemd's log rotation.


This didn't happen with Fedora 21. I'm running under GNOME Shell -- I have not tried other environments.

A bug filed in Fedora https://bugzilla.redhat.com/show_bug.cgi?id=1215329 has additional logs from another tester who was able to reproduce.
