I have just rebooted 2.6.10 with this LILO command line

    LILO Boot: Linux-2.6.10 noapic

and if that disables APIC, then I've got the same problem. After 
suspending the laptop
two times, I get the same lines (described below) and the usb system 
goes nuts. After
removing & inserting uhci_hcd everything works fine again.

The lines are (endless loop):
drivers/usb/input/hid-core.c: input irq status -84 received
