I recently did two upgrades in the course of a few days...upgraded my
3.3-STABLE to a more recent version, and added hard drives onto the
system...now I'm getting SCSI problems that make no sense :(
The machine just hung once more, which its doing every few hours...I can
get down to the debugger, but a 'trace' doesn't appear to show anyting, so
I panic...

======
I'm going to upgrade to the newest kernel, but none of the recent commit
messages *sound* like they are applicable...
A dmesg of the machine looks like, just in case either anything about the
controller/drives pops out at anyone?

=======
The QUANTUMs above have been in the machine for >1yr now and have worked,
from what I can tell, without a hitch...its only since we added da4+ that
we've seeing the problems...interaction problem between drive
manufacturers? I seem to recall this sort of thing being a problem on
older drives, but..
