aic7xxx-5.0.8 boot problem

[Michel Munnix]

after installing aic7xxx-5.0.8 (with linux-2.0.33), my computer looped
during boot phase with following messages:

(scsi0:0:4:0) Device reset, Message buffer in use
(scsi-1:-1:-1:-1) 0 commands found and queue for completion
SCSI host 0 channel 0 rest (pid 8) timed out - trying harder
SCSI bus is being reset for host 0 channel 0
(scsi0:0:4:0) Reset called, scb 29, flags 0x464

.... and so on (i could write down everything if needed)

while the previous driver aic7xxx-5.0.7 with the same kernel
worked fine.

disabling synchonous negotiation for scsi id 4 solved the problem for
aic7xxx-5.0.8

but why did it work previously with aic7xxx-5.0.7 ?

here is my boot log from aic7xxx-5.0.7
