Right.

Sure, no problem.

In fact, this issue is apparently scheduler independent. It indeed
seemd to be related to the other report we have "BUG: credit=sched2
machine hang when using DRAKVUF", but there it looks like it is
scheduler-dependant.

Might it be something that lies somewhere else, but Credit2 is
triggering it faster/easier? (Just thinking out loud...)

For Frederic, what happens is that dom0 hangs, right? So you're able to
poke at Xen with some debugkeys (like 'r' for the scheduler's status,
and the ones for the domain's vCPUs)?

If yes, it may be useful to see the output.
