--- Comment #2 from Vladimir Volovich <vvv at vsu.ru> ---
I'm using the package libgl1-mesa-dri version 10.2.5-1 from Debian sid. I
can try a different version if you'll let me know which one I should try.

I'm not sure at all what is the cause of this bug (whether it is related to
a kernel upgrade). I've been observing such problem for a several months
now. Usually it is triggered after opening many tabs in Google Chrome (i'm
using chrome unstable builds, such as 38.0.2125). When this was happening
on linux 3.14 and below, the problem was manifesting in having a segfault
in google chrome process, after which chrome was still running, but was
stuck (its windows became unresponsive). Restarting google chrome was not
possible, as it continued to be unresponsive. I needed a reboot to restore
things to normal operation. However after upgrading to linux 3.16, even
after receiving a segfault, chrome remained responsive, and I can still use
it (restarting it also works). I'm not at all sure where this GPU HANG
problem comes from.
