RE: [Xen-users] xen-unstable amd64 troubles
Thomas. What were you doing on the machine at the time? Was there a lot
of inter-domain or domain-to-external networking activity going on?
Which domain did the crash messsage come from?
Please post the diff of your config vs our -xen0 config.
Thanks,
Ian
