My Thinkpad R50P (Intel 82855PM with Speedstep 1.7GHz) shows the
following badness when resuming after an ACPI suspend - even if hotplug
and usb modules were never started beforehand: 

Mar 12 01:22:42 localhost kernel: 0 at 41

times                  Mar 12 01:22:43 localhost kernel: Kernel logging
(proc) stopped by user.

This is repeated many many times -> CPU usage jumps to 100% (due to
ehci_hcd module) and klogd becomes very busy with the above nonsense.

I cannot remove ehci_hcd, any attempt to rmmod will just hang, only
resolve is to reboot.
