Bug#789759: libdrm-nouveau2:amd64: X hangs, multiple instances of buffer 212 on validation list
Package: libdrm2
Version: 2.4.60-3
Severity: important
Package: libdrm-nouveau2
Version: 2.4.60-3
Severity: important
Dear Maintainer,
since some time, my X11 (running with Gnome) hangs often. This starts
with the applications not reacting to any input anymore, although the
mouse cursor still can be moved. After waiting some time, the system
seems to freeze completely.
In the log, I found the following messages before I did a hard reset:

Waiting longer also does not help (filtered for priority <= 3):
