OK. Seems to me that SUSE isn't configuring PCI properly on this specific system where Knoppix is. Using Failsafe, both acpi=off and apm=off _usually_ fix these problems in SUSE. My theory is that something in the BIOS or on the mainboard is activated/deactivated properly during a Knoppix boot while its missed during SUSE boot. Next step is to try other PCI and ACPI and possibly APIC settings on the boot command line. SUSE has 2 SDB articles for reference. The newest, http://portal.suse.com/sdb/en/2004/11/acpi_basics.html explains a bit about PCI, APM and ACPI. It references http://portal.suse.com/sdb/en/2002/10/81_acpi.html where we get some parameters to play with. What we know doesn't work in SUSE: apm=off acpi=off Things to try in no particular order since I don't know which would be most effective in this case or in general: apm=off acpi=noirq = ? disable IRQ routing in ACPI apm=off acpi=oldboot = ? use ACPI only for booting apm=off acpi=off noapic = ? apm=off acpi=off lapic = ? apm=off acpi=off nolapic = ? And here is how to make them permanent IF we figure out what works: http://portal.suse.com/sdb/en/2002/12/fhassel_bootoptions.html Stan
