2.6.3-mm1 and aic7xxx

[Fabio Coatti <cova@ferrara.linux.it>]

I'm experiencing some problems with 2.6.3-mm1 release: on boot the system 
hangs trying to detect scsi devices, and the light on scsi cdrom flashes 
every few seconds. With 2.6.3-rc3-mm1 all works just fine, and I get this 
syslog entry:

Feb 19 22:23:15 kefk kernel: ahc_pci:3:6:0: Host Adapter Bios disabled.  Using 
default SCSI device parameters
Feb 19 22:23:15 kefk kernel: scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA

I've also noticed (only with 2.6.3-mm1) a "PCI BIOS passed non existent PCI 
BUS 0!" message when it probes ICH5, i.e.

Feb 19 22:23:15 kefk kernel: ICH5: IDE controller at PCI slot 0000:00:1f.1

system: PIV 2.HT/i875p (abit ic7-g), SMP kernel (SMT), 
gcc (GCC) 3.3.1 (Mandrake Linux 9.2 3.3.1-2mdk)

I can provide more details if needed, and any help will be appreciated.

Thanks.
