You can unbind ehci-hcd from the controller by writing the controller's
name to the "unbind" attribute in the appropriate sysfs directory. For
example, on my system:

# ls /sys/bus/pci/drivers/ehci_hcd
0000:00:1d.7 0000:01:00.2 0000:01:01.2 bind module new_id uevent
unbind
# echo -n 0000:00:1d.7>/sys/bus/pci/drivers/ehci_hcd/unbind

Then to rebind the driver, write the device name to the "bind"
attribute:

# echo -n 0000:00:1d.7>/sys/bus/pci/drivers/ehci_hcd/bind

Thanks, that works nicely and takes away the need to reboot when using a stock F11 kernel and the problem occurs.

I've recently discovered that I can provoke the error too, when using dd on an usb-dvd writing the output to an usb-hdd. So the topic of this thread is now certainly wrong.

And because I'm still having the problem using Kernel 2.6.31.7 and 2.6.32, I've written bug #14785. It's easier to attach long logs there.

Kind regards,
