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! ;-) > > > > > http://lists.xensource.com/archives/html/xen-devel/2010-02/msg00469.html > > > > Sounds like it could be related. Shall I apply that patch?
