2.4.22 USB problem (uhci)

[Jan Rychter]

Upon disconnecting an USB mouse from a 2.4.22, I get

  uhci.c: efe0: host controller halted. very bad

and subsequently, the machine keeps on spinning in ACPI C2 state, never
going into C3, as it should (since the mouse is the only USB device).

If afterwards I do 'rmmod uhci; modprobe uhci', then the machine starts
using the C3 state again.
