Oooh, share please.

Well, I am working on a PCI E820 hole thingie, but those patches are in the
infancy period. There are some fixes:

stable/xen-pcifront-fixes

but they aren't that .. sophisticated.

Hmm, so the difference between that and the upstream is the PVonHVM and
the initial domain 0 support (all in Stefano's tree).

I'll try disabling CONFIG_XEN_PVHVM and see if that helps. 

Either way I'll start filing the problems I'm seeing.

Thanks
