Bug Description
After the latest kernel upgrade, my system has many graphical glitches, and is locking up frequently. The dmesg output has errors like these:
[ 1951.568672] Watchdog[2753]: segfault at 0 ip 00007fe00773a32e sp 00007fdff869f680 error 6 in chrome[

Attaching /sys/class/ drm/card0/ error as directed in the dmesg. Could this be caused by a recent switch to SNA?
