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.
I read both. Thanks. :o)
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 = ?
OK, now I need specific guidance -- what to do, where, and how to get back to where I was if something doesn't work. Do I enter these changes at the Grub bootloader -- the same place where I was entering "3" before SuSE starts up? Do I still enter "3" or am I entering these commands instead and going into Failsafe mode? Let's consider the first one you suggest: apm=off acpi=noirq = ? Since apm=off is the default upon entering FailSafe, does this mean I enter acpi=noirq and go into Failsafe, then log in as root and try both sax2 -r and sax2 -l? If neither works do I power down, restart, get back to place where I was, enter Failsafe and type acpi=off to get back to default, then also enter the next of your options: apm=off acpi=oldboot = ? And do I then just keep going down the list until something happens or nothing happens? My biggest concern here is how to recover to default if something bad happens.
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
Have not read this one yet. :o) Gil
