Lars,

The only thing that seems to prevent this error for me is running an
older kernel. I'm running 2.6.32-22 now without any trouble. I haven't
checked at exactly what kernel version things start to go wrong, and I
don't think I will because I don't want to risk corrupting my data.
Maybe now that you are experimenting you can find out at what kernel
version things go wrong. We could use that info to post a bug on the
kernel bug tracker (as the launchpad bug tracker seems to be pretty
much useless for this kind of stuff).

If it turns out that you also experience problems with older kernel
versions we might not be suffering from the same problem.
