 21423 is still with us - we just tried to reboot a NetBSD 2.0.3 box that
 had a bad NFS mount (the server was down) with "shutdown -r", and it got
 stuck in the usual place (after the "Shutting down..." message but before
 "Rebooting...").  I had to get into the kernel debugger and issue "reboot 0x4"
 to get the reboot to proceed.
 
 Also, it's unclear to me how the problem in 28971 (a problem in readdir)
 could be related to the inability to unmount a bad NFS mount.
 
 Thanks,
