Wow!  I was going to post this same thing tonight... I got the same type
of error message today on one of my machines.  I run 4.0-RELEASE,
Adaptec 2940 v1.11 firmware, and a Seagate ST34371N.  I haven't had any
problems with the drive over the past 10 days since I installed it.

I recieved the error, while I was hitting the drive hard doing a 1GM ftp
and processing a 400M http log file using urchin.  I was wondering it if
might be a firmware problem on the 2940 or the drive revolving around
tag queueing.
