Bug 241685: graphics/drm-fbsd12.0-kmod in some cases makes X unusable
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241685



--- Description ---
I have Intel Haswell based laptop with drm-fbsd12.0-kmod on 12.1-STABLE
installed.

When I run Firefox, Xorg starts to consume 10% of CPU and system becomes
unresponsible to user input. Even if I close Firefox, system still in this
state until I reload the graphical session.

With old i915 and drm2 that still in the tree for 12.1-STABLE everything works
fine.
