Now, I think, you may really go ahead! ;-) 'nopat' did the trick for me.

Hmmm... I rethought the workloads I had and found a way to reproduce the
crashes -- more or less reliably:
As I did a complete reinstallation of my notebook, I had a lot of data to
copy. The first bunch of sutff was copied on Dom0 -- this was where I
experienced the crashes; not immediately while copying but a little later
(The warnings in the syslog always happened during copying, btw).
Then -- after I basic setup was done -- I used xm block-attach and copied
tons of stuff within a DomU. I did not experience a single crash while
doing so.
Do you want me to do something to further debug the issue? Just tell me
what I could/should try to do! ;-)

Yes, I will! ;-)
