I have this with 18_rc6 and 18_rc7 also:

In older Kernels or even 2.6.17 I never saw this.
So may be the initial report was barking at the wrong tree, this is a
plugged wired USB keyboard (daskeyboard.com).
The Keyboard is fully functional while typing on it and this happens
without being in X. It happens with nobody logged in local, the messages
are logged even only when logged in via ssh.

libusb and usbutils are not installed on this machine (should they?).
