[Xen-devel] dump with xen-unstable & linux 3.2.17

I'm attempting to update the Xen I'm using, and am having an issue with S3.
Konrad - I know you've been down this path before - so I'm hoping you
might have some insight, given the stack below

The linux tree also has an older version of Konrad's acpi-s3
development branches (it was v7)

Upon resuming from S3 - Xen panics with the following stack. I'm
guessing it has something to do with some of the pcpu work going on
recently - but haven't been tracking this too closely, so am not sure.
The same kernel with Xen 4.0.x works OK.
