Using IDE? ;-)

No for sure, I'm using 12 75GB IBM disks in a NAS proto type and
having quite the same, but it didn't really hang but took about one
hour before something really happens. Meanwhile I could log in on ttyx.
Using 5 72gb (I couldn't afford more) SCSI is working great. So I'm
pretty sure it's IDE. (vinum with RAID4 or 5)
