Aic7xxx troubles with 2.4.1ac6

[Ville Herva <vherva@viasys.com>]

It looks like ac6 (which I believe includes the patch you posted) is
still a no-go with 7892. The boot halts and it just prints this once a
second:

(SCSI0:0:3:1) Synchronous at 160 Mbyte/sec offset 31
(SCSI0:0:3:1) CRC error during data in phase
(SCSI0:0:3:1)   CRC error in intermediate CRC packet

This happens also with ac5+the small patch you posted earlier. ac2 works
fine (although something did corrupt my MBR while using it. It is still
a complete mystery to me what could have done it. Now I'm unable to
boot NT; linux of course works with the boot floppy.)


ac2 dmesg's:
