Distribution: Fedora Core 1

Hardware Environment:
Asus CUV4x-D BIOS 1016
Adaptec 29160 (aic7892 bios 3.10)
   - 1st drive ID 0: Seagate ST31846LW
   - 2nd drive ID 1: IBM DPSS-318350N (BIOS S80D)

Software Environment: aic7xxx driver version 6.2.36 of kernel 2.4.22
of fedoracore 1

Problem Description: When loading the aic7xxx driver module it writes
down:

scsi0: Unexpected busfree while idle
SEQADDR == 0x1
---> loops for a while <---
* CRC Value mismatch(scsi0:A:0:0): parity error detected in Data-in
phase SEQADDR(0x6c) SCSIRATE(0xc2)
---> note: I've also seen SEQADDR(0x7d) while making tests <---

Steps to reproduce: Just plug in the IBM SCSI drive.

How reproducible: everytime

Additional info:

Here is some more info while using aic7xxx_old driver instead which
works prettywell.
