Exactly the same here on Debian/Unstable 2.6.5-rc2.

Though I can't say it locks up on. Remove modules manually
rmmod ehci_hcd
rmmod ohci_hcd

Usually it takes some time and eventually rmmod returns successfully
removing modules !

In my case when system boots up - USB mouse is not working.
If I remove and reinstaer ehci_hcd and ohci_hcd - everything seems fine.

$ ps -C rmmod -o pid,uid,state,wchan=WIDE-WCHAN-COLUMN
PID UID S WIDE-WCHAN-COLUMN
1844 0 D usb_disable_device
2209 0 D rwsem_down_write_failed

Perhaps that will help ...
