--- Comment #5 from Michel Dänzer <michel at daenzer.net> ---
http://lists.freedesktop.org/archives/dri-devel/2015-June/084514.html fixes the
hang for me (not a GPU hang but a kernel hang, because it tries to lock a mutex
that's already locked).

These still happen, but at least with GNOME it continues working for me
somehow. I tried various workarounds for this in the Xorg driver, but I haven't
found anything that avoids these. I think the proper solution for these would
be for the kernel driver to track GPU VA ranges per GEM handle instead of per
BO.
