Two of the bugs are actually the same guy. One of the others is x86_64 the other two are 32b. The only thing in common about the stack traces is that networking functions seem to feature. Taking a wild guess, are you doing some kind of unusual networking setup involving iptables rules? > Do we have any consensus that this bug is fixed at all in > xen-3.0-testing, or even unstable?

It's unlikely to be a hardware issue, and since the problems seem to be experienced by a very small number of users my guess would be that it's configuration dependent, most likely networking. > If anyone needs any more information, just let me know.

Having a really detailed bug report would really be the best way of proceeding. When this happens, does it just effect one guest? What's the stack trace? How many VCPUs has the guest got? Is the guest completely hosed or is it still pingable? What about guest console echo? What about 'xm sysreq'? Looking in dom0, are you still seeing packets go to/from the associated VIF? How many network interfaces has the guest got? What's the precise networking setup in dom0? Can you come up with a recipe for reproduction, ideally with a single guest?
