Kernel upgrade to 2.6.21-1.3228.fc7 means usb keyboard stops working frequently

[Paul Johnson]

Anybody seen this after a kernel upgrade?  The usb keyboard is "dead",
but I can log in with ssh and the dmesg output if full of hundreds of
lines like this:

hub 5-0:1.0: connect-debounce failed, port 2 disabled
printk: 2 messages suppressed.
hub 5-0:1.0: connect-debounce failed, port 2 disabled
printk: 3 messages suppressed.

If I power down all the way and restart, then the keyboard works, but
as soon as I log out and try to log in again, then the gdm won't let
me type and the /var/log/messages fills up with those errors again.

Ideas?
