[BUG 2.5.25] ide-scsi oops

[=?ISO-8859-2?Q?Witek_Kr=EAcicki?=]

Tested on 2.5.25dj2 and 2.5.25dj2 w/IDE97
Configuration:
Asus a7m266 with Via IDE
hda: Seagate Barracuda
hdb: LG DVD
hdc: LG CD-RW
hdd: empty
When using 'ignore=hdb' or without any ignores while loading ide-cd ide-scsi
loads without problems. In any other configuration (without loading ide-cd,
loading with 'ignore=hdc') ide-scsi loading causes following oops:

Usually (but not always) about 30secs after loading ide-scsi there is a
kernel panic (sth with SCSI, I'll try to rewrite it on my second PC).
