Hi!

I just built a new -CURRENT world/kernel on my laptop for the first time in
two weeks, and I'm being flooded (a few per second, not timed exactly) with
messages like:

  Jan  5 08:49:29 hermes kernel: usb0: 1 scheduling overruns
  Jan  5 08:49:29 hermes kernel: usb1: 1 scheduling overruns
  Jan  5 08:49:29 hermes kernel: usb2: 1 scheduling overruns

Could these possibly be ACPI-related?  I only get these messages when I'm
running on battery power.  As soon as I plug AC in, the flood stops.  Also,
I've always had 'scheduling overruns' when putting my laptop to sleep (I
posted to the list about that a few months ago iirc), which makes me think in
the same direction.

Any idea how I could go about debugging (and preferably fixing :-)) this, or
what information I could provide to allow a more talented hacker to fix it?

Thanks!

 - Philip
