Hello,

I have experienced a dom0 crash where the system became unreachable via the
network and the console was unresponsive.  I would appreciate help
interpretting the logs and any configuration change suggestions.

It is a stock Debian Lenny dom0 running xen 3.2.1 with kernel
2.6.26-2-xen-amd64 and an AMD Athlon IIx4 with 4 GB of RAM.
    

that's a somewhat old, known-to-have-bugs kernel. The bugs might not
be directly related to your problems though.
  

This is the stock debian stable (lenny) kernel.  Bug fixes are typically back-ported by debian maintainers, so I would be surprised if the kernel is the issue.

I'd start by making sure the HW itself is fine (perhaps by booting a
normal, non-xen, known-good kernel and doing something like "dd
if=/dev/sda of=/dev/null bs=1M").
  

I'll give this a shot and let you know what I learn.  The hardware itself is less than a week old and I haven't done any serious testing.

Have you tried latest opensuse xen kernel?
http://code.google.com/p/gentoo-xen-kernel/downloads/list

  

Not yet, I'll try loading the I/O as you've suggested above with with my existing non-xen debian stable kernel first and see how it goes.  If that causes problems I'll try again with 2.6.32.11 and the patches from your link.

Thanks for the responses!
