It was a fix. We had some interrupts getting wedged - but I don't recall the stack exactly. But there are some follows - like e5ac0bda96c495321dbad9b57a4b1a93a5a72e7f 7e186bdd0098b34c69fb8067c67340ae610ea499 > > Might the tsc unstable message be relevant? Hm, not sure. I keep on getting those on my guests but life seems to go on. The interesting about the stack trace is that it looks similiar to: http://groups.google.com/group/linux.kernel/browse_thread/thread/39a397566cafc979 which has some fixes https://patchwork.kernel.org/patch/1091772/ but they may not help. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".
