I'm having trouble when accessing a dos or vfat partition. After the
device has been mounted, when any simple commands are executed (e.g. cd, ls)
I recieve the following messages:

scsi0: Queue full.
scsi : aborting command due to timeout : pid 75325, scsi0, channel 0, id
0, lun 0 0x08 0b 5e ca 01 00
aic7xxx: (abort) Aborting scb 2, TCL 0/0/0
scsi : aborting command due to timeout : pid 75326, scsi0, channel 0, id

aic7xxx: (abort) Aborting scb 1, TCL 0/0/0
scsi : aborting command due to timeout : pid 75325, scsi0, channel 0, id

aic7xxx: (abort) Aborting scb 2, TCL 0/0/0
SCSI host 0 abort (pid 75325) timed out - resetting

Followed by the controller resetting. I am running a monolithic kernel.
I have a 2940UW and a Quantum Atlas 4.3GB HD which is fast/wide SCSI II.
I have the Ultra SCSI turned off, and the drive's x-fer rate set to
20MB/S in the BIOS of the controller. Sync negotiation is also turned on.

Any ideas?
