Hi Keir,
> What type of CPU are you running?
2x Intel Xeon 5120 (Dual-Core), running the 64bit hypervisor.
> Is it valid retail silicon?
what do you mean by "valid"? at least xen 3.0.x, and 3.1.x worked on it
without any problem before. It seems that just a change between 15590 and
15598 must have broken something.
It's not a dell, hp or ibm branded system, but it's quite a normal
intel-based system.
intel board (S5000PSL)
intel chipset
intel e1000 lan
lsi megaraid_sas based sata-controller
8GB RAM

yep, it says:
