Hi Linus & James,
I've still got problems under 2.6.13-rc6 with my DLT7000 drive on an
AIC7880 builtin controller. Here's the message I got in dmesg. My
system is a heavily upgraded Debian/unstable with dual 550mhz Xeon
processors and 768mb of RAM, dual SCSI busses. The annoying problem
is that I have to (sometimes) power cycle the DLT 7000 tape drive to
get it back onto the bus. So I guess it could be a tape drive
problem, esp since I've got my root disk on /dev/sda, which is also a
builtin AIC7890 controller. Sometimes I'm able to do a 'scsiadd -r 1
0 6 0' and then a 'scsiadd -a 1 0 6 0' to get it working again.
Details about my system:
