Unfortunately I haven't written down the panic message (I thought that I
could retrieve it using gdb when the sever crashed), so unfortunately the
only thing useful I have right now is /var/crash/info.1:
# cat info.1

Of course there is also vmcore.1 but this file is huge and I don't really
want to post it somewhere available to the public as it might contain
sensitive information. In case somebody might be interested in, I've put
the output from dmesg, pciconf -l -v and the current Kernelconfig here:
