Greg,

After learning how to do this stuff, I'm back :)

I am now at 10 crashes since Sunday, and counting.

Anyway, I don't know much about gdb, but here is what I was able to get
from my most recently dumped kernel:

http://docs.perimeter.co.za/crash/20020823_1623_d

As the name indicates, this was at 16:23 this afternoon.  Others on the
hacker list have suggested you would be THE person to speak to WRT what
appears to be a fault occurring in the vinum module somewhere.

There was a suggestion that the fault might lie in the fact that one of
my IDE controllers is "falling back to PIO" because I don't have the
ATA100 compliant cable on device ata1.  I'm hoping to get to the server
on Monday to replace that.

There is more info at http://docs.perimeter.co.za/crash/

Looking forward to your response,

Regards,
Patrick O'Reilly.
