Re: Linux-2.6.13-rc6: aic7xxx testers please..

Hi James,

Dropped back to 2.6.11.1 and it hung again.  I was able to get the
drive back by power cycling it and then doing the scsiadd to drop and
re-add the drive.  I then used the bacula 'btape' tool to run some
tests.  It seems to be just fine with regular files, but when it hit
EOM, all hell seems to break loose.

There is newer firmware available for the drive, so I'll see about
upgrading the firmware ASAP and see if that happens.  Unfortunately,
it's a SUN branded DLT and I don't have sun hardware at home.  

Here's the latest dmesg error logs:
