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,
Alexander Holler
