I just upgraded the BIOS of my A8V deluxe to the newest version (1014) und tried to boot with the Suse 9.3 Live-CD, distributed by the German magazine c't.

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} <ffffffff80152e48> {__do_IRQ+216} <ffffffff80111132> {do_IRQ+66} <ffffffff8010ecc7> {ret_from_intr+0] <EOI> <ffffffff8010d560> {default_idle+0} <ffffffff8010d580> {default_idle+32} <ffffffff8010d986> {cpu_idle+54} <ffffffff804d670a> {start_kernel+442} <ffffffff804d6240> {_sinittext+576} 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? Ciao Siegbert
