 I can't replicate this on NetBSD-current i386.  
 
 What command are you using to reboot?  Are there any indications in 
 the shutdown messages about being unable to unmount / ?  I.e. does it 
 look like this:
 
 syncing disks... 3 3 3 done
 unmounting file systems...
 unmounting / (/dev/raid0a)... done
 rebooting...
 
 or something else?
 
 Thanks.
 
 Later...
