Hi,
i am seeing a deadlock on removal of the ohci_hcd module. You get to see
some usb disconnect messages after which the machine is dead and needs
to be powercycled. This is a Sony Vaio C1MHP. I am unable to test 2.5.70
because it hangs on boot with unhandled IRQs.
This also happens when unloading the usb-storage module beforehand.
