Recent time I've encountered a problem with 2940 adapter and new IBM
Ultratar.
BIOS detects all of HDD (SCSI ID 0,1, 4) during bootup correctly. int13
seems to work correctly too. When linux kernel (2.2.14) tries to load
aic7xxx code, two older (0,1) drives are waking up correctly. New one
(SCSI ID 4) makes timeout and driver module goes into infinite
reset-timeout cycle.
I have done some work to repair this, but have no success. And now I
think I will
gladly use following bootup options to help myself:
aic7xxx=bad_id:list - Never try to work with devices with SCSI ID
from list. Just forget about this.
aic7xxx=SCSI_DELAY:secs - set delay time after resetting the SCSI bus to
wait until trying to communicate
