</span>ps -axl shows PID 1394 (umount) waiting on tstile, which is used for<br>
spinlocks. No process should sit there for long, unless there is a<br>
kernel locking problem (which may be a userland locking problem<br>
thanks to FUSE).<br>
<br>
Using crash(8) I can see umount is awaiting for a vnode lock. There<br>
is certainly something to investigate but I lack time for now. I<br>
issued a reboot. Please tell me if you can reproduce it.<br>
