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?
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.
