I'll try to repro. You're crash happened very early in resume. Is your xenbus driver the built from tip?

Yes I updated all to latest git in http://xenbits.xen.org/gitweb/?o=age, all except xeniface was updated if I remember good.

Was happen 2 time on total of 5 save/restore I tried.

Latest test was with qemu upstream updated including also the new 2 xen bugfix http://git.qemu.org/qemu.git (commit 4e70f9271dabc58fbf14680843bfac510c193152).
