problem with adaptec aic 7895

Hi, I have a problem with this controller. When I boot linux I receive
this error:

scsi : aborting command due to timeout : pid 23, scsi1, channel 0, id 0,
lun 0, Test Unit Ready 00 00 00 00 00
(scsi1:0:0:0) Aborting scb 14, flags 0x4
(scsi1:0:0:0:tag14) matches search criteria (scsi1:0:0:0:tag14)
(scsi1:0:0:0) SCB found in QINFIFO and aborted.
(scsi1:0:0:0) Aborting scb 14
(scsi1:-1:-1:-1) 1 command found and queued for completion.  

kernel 2.0.36 + AIC 5.1.6 patch

My question is: may I disable the scan for scsi1? All SCSI devices are
in the channel A: scsi0.

Thanks,
Giuseppe
