--- Comment #23 from Tom London <selinux at gmail.com> ---
Updated to xorg-x11-drv-intel-2.20.17-1.fc19.x86_64, reran my "disk load" test
("cat bigfiles >/dev/null"), and waited.

Within about 2 minutes gdm/Xorg hard crashed, the screen was black, and the
system was unresponsive to the usual keyboard entries (i.e., ctrl-alt-F2,
ctrl-alt-bksp, ctrl-alt-delete).

I did not get the "gdm Ooops something has gone wrong" screen.

I had to hard power reset the system.

On rebooting, I see this in /var/log/messages.
