>Description:
When I try to make a backup on DAT (the python) the machine goes down quite
frequently. This makes it impossible to make backups (localy) of this machine :(
I tried this with my ahc-2940 which i normally use and with a ncr53c810 card (asus2000)
from my linux-machine. The ncr-driver doesn't give as much information, but the problem
is the same. The tape works fine on the other (linux) machine with the ncr-card.
I run cvsup frequently (twice a week or so). This problem has existed for a few months
now. (it used to work better with 2.1.0).
The machine is in use as my proxy and news-server, other than this FreeBSD is
running like a charm! Keep up the good work people =)
>How-To-Repeat:
If needed i can give access to the machine and mount a blank tape. To repeat the
problem a simple 'dump 0uBf 2000000 /dev/rst0 /' will do I'm afraid :/
>Fix:
Yes, please do.
kind regards,
Frank Ederveen
