I remember a similar bug around 2.99.917 but that tag is over a year
old now and there have been many bug fixes since. You'll need to
verify you can still reproduce your issue with the latest from
git://anongit.freedesktop.org/xorg/driver/xf86-video-intel and if so
do a bisect from the previous working kernel or xf86-video-intel to
identify the problematic commit.
