Just for me for clarification: So is it reasonable that my server crashed
with th #3 patch used, or is this something I should investigate furthor /
maybe do another xen build.?

Also, I don't have a serial port, but i got a netconsole setup running. Is
there any way to pipe the xl dmesg output into the normal dmesg output so
it would be caught by netconsole?
