I think you meant another branch....but I don't believe the problem is related
to the pcifront. Boris was able to trigger this without using the XenPCI front.

It might make more sense to bisect from 2.6.36 through 2.6.36-rc1 timeframe.
During the merge window time when a lot of patches went in. It seems to point
to network since that is how you guys are triggering it..

Ah, that would be the stable/xen-pcifront-0.8.1 tree. And it was based off
v2.6.36-rc7. There is also the stable/xen-pcifront-0.8.2 tree 
(5bba6c56dc99ff88f79a79572e29ecf445710878) - which for some mysterious
reasons on git.kernel.org was tracking the #master branch, so it ended up
pointing to stable/xen-pcifront-fixes.. I fixed it, but that one 
(xen-pcifront-0.8.2)
is based on v2.6.36-rc6, so even older (that was required as it was based on 
sparse_irq
rework).
