I also get a bunch of messages almost like this one when starting X. I
am running X.Org 6.9.0 on -current from January 28 (userland from Jan
26), and X is working well despite these warnings. See the attached
/var/log/messages.

Jan 29 22:18:51 anduin kernel: malloc(M_WAITOK) of "16", forcing
M_NOWAIT with the following non-sleepable locks held:
Jan 29 22:18:51 anduin kernel: exclusive sleep mutex drm device r = 0
(0xc2edfcd4) locked @
