The reason for having to reboot your system hanging is that if try and
kill the process it causes a 'defunk' process, apparently you can kill
process like 'tar' or 'cpio'.

I must admit I have had some customers with the same problem. I have seen
on the BBS that SCO are now working on a fix for Wangtek. It did not say
for which tape drive (60 MB or 150 MB), but was due for release soon.
