[ 21.396440] Kernel panic - not syncing: HOST_MSG_LOOP with invalid SCB ff The panic is generated by the driver code used for various Adaptec SCSI adapters. I think that this error would normally indicate a fault in the SCSI adapter and the driver should not panic, but that may not be easy to avoid. However, since the 486 kernel works, the fault is clearly in software. Could you test the 686 kernel with the added kernel parameter 'maxcpus=1'?
