Hi all,

I've had a report of a host starting to give this output:
Oct 7 19:36:37 kernel: INFO: rcu_sched self-detected stall on CPU { 2}
(t=273561 jiffies g=17919 c=17918 q=9688)
Oct 7 19:36:37 kernel: sending NMI to all CPUs:
Oct 7 19:36:37 kernel: xen: vector 0x2 is not implemented

Kernel is 3.11.2.
Xen is 4.2.3.

I've seen various random reports of this, but never a follow up on what
seemed to be the issue or a fix. The latest was on the ARM platform, but
may be a different issue.

Has anyone come across these before and found a solution?

Xen 4.2.2 seems unaffected.
