Hi! I've upgraded my system to 14.3-BETA3. Now sometimes right after the
system boots up I have this message:

Fatal trap 12: page fault while in kernel mode

Also I have this message since 14.0 or so (these two seems to appear
independently):
drmn0: [mmhub] page fault (src_id:0 ring:157 vmid:0 pasid:0, for process
 pid 0 thread  pid 0)

My drm module is 6.1.92.1403000_3 (I recompiled this version after updating
to 14.3). My GPU is AMD's dimgrey cavefish.

The system works as usual despite the messages. Do I need to worry about it?
