>Description:

I tried upgrading a machine to a 4.99.30 GENERIC kernel built from
-current sources of September 4, 2007.  When booting the new kernel,
there was a pause of about a minute after the cd1 probe.  Then
the kernel printed the message

 uhub0: device problem, disabling port 2

and continued booting.  When the login prompt appeared, the USB
keyboard was unresponsive.

The keyboard works at the boot prompt, but if I enter "boot -c" to
invoke userconf, it no longer works at the userconf prompt.

The problem appeared some time between 4.99.6 (which works fine) and
4.99.15 (which fails the same way as 4.99.30 except that it lacks the
one-minute pause).

The motherboard is an ABIT KG7 RAID.  Here's the dmesg output:
