io scheduler cfq registered (default)

without an error, it might help to turn EHCI Hand-Off in BIOS on. This fixed the problem for me. When this option is missing, revert back to 2.6.25 and look for a line looking like this:

EHCI Handover failed - BIOS Bug?

When a line like this exists, a BIOS update might help.

Maybe this helps someone.
