Weird SCSI Errors, AIC 7880

Greetings All,
I'm seeing some strange errors from a newly set up RH 7.3 box. The
machine is a P-I 200, with an Adaptec 7880 (older 2940). On this machine
I have two quantum fireball ST2.1S model 2.1 gig drives.
The machine is setup with both drives mirrored to eachother in a
software RAID 1 array. The kernel version is box-stock, 2.4.18-3, and
the AIC7xxx driver version is 6.2.5.
Not too long after completing the OS install (the RAID array was built
during the install) I started seeing a number of SCSI errors I've never
seen before. Suspecting that one of the drives might be going bad, I
checked both with smartctl, but both drives appear to be fine.
The SCSI errors in the logs are numerous, but here's a good sample of
them (mostly in sequential order); I'll include a cat of
/proc/scsi/aic7xxx/0 at the end.
TIA for any and all advice/pointers,
--Duncan
