gdb_log

Cauldron with kernel 3.15.1, server 1.15.99.903 and driver 2.99.912 was OK.
Cauldron with kernel 3.15.1 & 3.15.6, server 1.16.0 and driver 2.99.914 segfaults.
Factory with kernel 3.16.0, server 1.16.0 and driver 2.99.914 segfaults.

I don't build, so cannot bisect directly unless someone else provides rpms. If the driver rpm really only has one binary that matters in it, with some help I could possibly copy it/them from other [Cauldron|Rawhide?|Factory] installations upgraded in recent weeks and months to narrow the timing down some. At this point I have no idea if any of them have 2.99.913.

Hi Chris.
Next time, could you tag such commits more explicitely, such as adding the [segfault] keyword so that we (distro packagers) can notice them and backport them?
Or you could alternatively do updates releases for such bugs (eg: 2.99.914.1)

More explicit than "REGRESSION in i810"?
