Distribution: Debian Testing Hardware Environment: Asus PR-DLSW Mainboard ASUS PR-DLSW ACPI BIOS Revision 1008 Software Environment: gcc-2.95.4 Problem Description: o Can only boot with acpi=off or acpi=ht o System fails to boot when ACPI support is enabled. Doesn't detect all PCI busses / controllers: VFS: Cannot open root device "801" or unknown-block(8,1) Please append a correct "root=" boot option Try booting with pci=noacpi, acpi=ht, or acpi=off on the command line. If one helps, please report the following lines: DMI: BIOS: Award Software, Inc., ASUS PR-DLSW ACPI BIOS Revision 1008, 09/25/2002 DMI: System: System Manufacturer, System Name, System Version DMI: Board: ASUSTeK Computer INC., PR-DLSW, REV 1.xx Kernel panic: VFS: Unable to mount root fs on unknown-block(8,1) o System hangs with pci=noapci scsi0 : sym-2.1.16a sym0:0:0: ABORT operation started. sym0:0:0: ABORT operation timed-out. sym0:0:0: DEVICE RESET operation started. sym0:0:0: DEVICE RESET operation timed-out. sym0:0:0: BUS RESET operation started. sym0: SCSI BUS reset detected. sym0: SCSI BUS has been reset. sym0:0:0: BUS RESET operation complete. sym0:0:0: ABORT operation started. sym0:0:0: ABORT operation timed-out. sym0:0:0: HOST RESET operation started. sym0: SCSI BUS has been reset.

Please reference bug#10 , It looks like a similar issue fixed there.
The link with the info doesn't answer, so I've got nothing to work with here. If you're running the latest BIOS and the latest 2.4 or 2.6 kernel still fails, please re-open this bug and attach the acpidmp and dmidecode and dmesg from the acpi=ht case.
Created attachment 1797 [details] dmesg with acpi turned on
Created attachment 1798 [details] dmesg with acpi=ht
Created attachment 1799 [details] dmesg with pci=noacpi
Created attachment 1800 [details] output of dmidecode
Created attachment 1801 [details] acpidmp output
>ACPI: PCI Root Bridge [PCI0] (00:00) >ACPI: PCI Root Bridge [PCI1] (00:00) >ACPI: PCI Root Bridge [PCI2] (00:00) the same problem as bug 1162
oh, oops, should be the same as Bug 1662
