Yes.

The XEN and CPU config options are identical to the configs that come as
defaults. Just a lot of devices drivers are not compiled in.

The hard disks are attached to two 3Ware/AMCC SATA storage controllers
(9550SXU-8L), the NIC is an intel PRO/1000.
When crashing the system, I am not involving the NIC, just traffic on
the internal bridge.

Yes, I removed the DIMMs. I'm just testing with 8GB. Should I try
limiting the memory with mem as well?

Yes, possibly. We will also test some BIOS options related to memory.
I'll give you feedback if we figure something out.
