Once paused and state saved, everything is correct, and no problem on the
xen log.

After restore, the VM reply to ping, but ssh (with key, no passwd) doesn't
show the banner and the prompt until I press return. Any other key is not
processed.

No more action could be executed except destroy.

I've tried on 64bits squeeze, and it's the same except ping and ssh
doesn't
work.

reassign 644604 linux-2.6
forcemerge 644604 654850
thanks

This is the same as #644604, please update your domU kernel to at least
2.6.32-39 from stable-updates.
