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
