The boot log of this case is attached as "2.6.13.4_without_remapping.txt". If I however enable BIOS memory remapping to make full use of the 4GB RAM, the boot fails within the scsi driver routines. This boot log is attached as "2.6.13.4_with_remapping.txt". The kernel I used for this test is a quite minimalistic, static (i.e. without modules) vanilla kernel; its config file is attached as "config-2.6.13.4". I also tried to boot with the newest SUSE 10.0 CD in rescue mode, which uses a kernel with modules. The result is mostly the same. I attached the boot log with disabled BIOS memory remapping as "SUSE-10.0-RESCUE-2.6.13-15_without_remapping.txt" the log with enabled BIOS memory remapping as "SUSE-10.0-RESCUE-2.6.13-15_with_remapping.txt". The last one was caught in a loop, so I rebooted by SysRq. On the SUSE AMD64 mailing list there was a report of a success with the A8V (same BIOS), 4GB of RAM and BIOS memory remapping enabled, where the only apparent difference seemed to be, that this was an IDE system, whereas mine is a SCSI one. As booting always fails in the scsi part, I suspect an error in the aic7xxx driver. Steps to reproduce: Boot any recent kernel on a machine with an Adaptec 19160B, Asus A8V and 4GB of RAM. ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
