Which is a 32 Bit version AFAIK.
After some more experiments over the weekend, I found out, that the 
Live-CD is indeed 32bit only (despite the boot screen offering a 64bit 
version, too), but the "rescue" and "installer" options really offer a 
64bit kernel.

The bad thing is, that (with BIOS memory remapping enabled) booting the 
"rescue" option in 64bit mode fails. Still in the SCSI part, as it was 
already true for Suse 9.2.
$ /sbin/lspci|grep SCSI
0000:00:0d.0 SCSI storage controller: Adaptec AIC-7892B U160/m (rev 02)

Just to mention: Booting 64bit mode without BIOS memory remapping works 
as well as 32bit mode with BIOS memory remapping. In the latter case I 
only get 3GB of RAM, because the 32bit kernel on this Live_CD is not PAE 
enabled.

Can any of the Suse people here have a look at the error messages, I get 
when booting our SCSI system?

On tty1 I see:

scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
(scsi0:A:6): 160.000MB/s transfers (80.000MHz DT, offset 127, 16bit)
scsi0:A:6:0: Tagged Queuing enabled.  Depth 32

Then on tty2 there is a storm of messages always repeating th same two 
lines:

scsi0: PCI error Interrupt at seqaddr=0x97
scsi0: Received a Master Abort

Then after some time this stops and I see:

irq185: nobody cared!

call trace: <IRQ> <ffffffff801532c0> {__report_bad_irq+48} 
<ffffffff80153389> {note_interrupt+89}

handlers:
[<ffffffff8815fa0>] (ahc_linux_isr+0x0/0x220 [aic7xxx])
Disabling IRQ #185

Afterwards the machine is frozen.

Any insight?
Is anybody running a 9.3 system on an A8V with SCSI, >=4GB RAM and BIOS 
memory remapping enabled?
Should I direct this problem to the linux kernel mailing list or who 
else could be interested in those BIOS memory remapping problems?
