I am not on Broadwell hardware.
I'm using a PowerEdge R300 machine,
with a Xeon x5460 CPU.

That is unfortunate.
Can you run `addr2line -e xen-syms ffff82d080217ae2` to find out
exactly which line the crash is from?
What kind of domain are you running? It looks like an HVM domain.
If so, can you possibly also, from dom0, run `xen-hvmctx $DOMID`
before attaching debugging?
