I'm experiencing the same thing sporadically with two machines running a handful of KVM VMs. It usually starts with one VM blocking, then spreads to the rest, and eventually the host itself stops responding.
I cherry-picked the three patches in LP 276476 and applied them to the 2.6.28 kernel currently in sid. So far so good, but I don't have a solid test case to reproduce and it usually takes a couple days for this to show itself. john -- John Morrissey _o /\ ---- __o [email protected] _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__ -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
