Hi
After suspend-resume on my Thinkpad T490 dri driver fallbacks to swrast.

On system boot:
  % xdriinfo
Screen 0: iris

After suspend-esume:
% xdriinfo
libGL error: failed to authenticate magic 1
libGL error: failed to load driver: iris
Screen 0: swrast

Logout from KDE session and login reverts driver to iris.

Some information about my system:
  - Thinkpad T490 with Intel UHD620 graphics
  - FreeBSD 14.0-CURRENT #22 main-n261913-3f0083c4e30a
  - drm-515-kmod-5.15.25_1
