(In reply to Eric Camachat from comment #4)
Can you reproduce with llvm39? On what FreeBSD version? Can you press Ctrl+=
T to
check wait message[1] ?

I have a similar issue on 12.0 amd64 (with drm-next merged) where the proce=
ss
is stuck on [umtxn]. Prepending LD_PRELOAD=3D/lib/libthr.so.3 makes it work=
 fine.
The first bad appears to be base r319971, bisecting which is complicated by
FREEBSD-diffs.
