yes (it's the same test) and yes (it appeared to be fixed but is broken now).

Is this the same 'ping other domain while diffing large files' test
that we were using to trigger the blkdev mismerge bug? If so, did
everything seem to work okay for a short while after that bug was
fixed, but has become broken again now?

If this is a bug that triggers after DOM0's memory map is mixed around
(no longer contiguous) then it may be easier to find after I add code
next week that will reverse DOM0's address space if you make a debug
build of Xen. It's already found one bug (in pci_alloc_consistent())
that I'll fix on Monday, and check the debug code in at the same
time.
