I had this symptom recently on an Asus PR-DLS533 mainboard
(ServerWorks GCLE chipset) with linux-2.4.21 and found out
it happens only if I had BIOS "USB legacy support" enabled.
As soon as I disabled this BIOS option, the phenomenon
disappeard.
For more info look for lkml thread with subject "system clock
speed too high?", Message-ID <3EDBA83B.5050406@xss.co.at>
