I haven't been able to pin it down to SCHED_ULE, but three times since I
switched schedulers, I have noticed that doing a clean "shutdown -r" after a
buildworld resulted in the filesystems failing to unmount.  A background
fsck was forced on all of them at reboot, but no problems were found and I
haven't noticed any data loss.  I just switched back to SCHED_4BSD, to see
if it continues, but it was only once every 3 or 4 reboots.
