That is sad to hear, however, it may be that it is a problem with wrong
interrupt routing in connection with an ACPI bios, or the APIC

Have you tried any or all of the options:
knoppix acpi=off noapic pnpbios=off

At last resort, you could try

knoppix nousb2


knoppix nousb

to disable USB2, or USB completely.

It may well be that a BIOS update would fix the problem. The early 64
athlon boards are known to have bad BIOSes, especially when running in
32bit mode. Since the newer kernels support AMD64 better, maybe some of
the boards components were not even detected in the older KNoppix
versions, and therefore there was no interrupt problem with them.
