Subject: [BUG?] warning from native_smp_send_reschedule() in 3.4.

Hi,

Often (but not always) on reboot I get warning from
native_smp_send_reschedule(cpu == 1).

It's a big 4-socket machine.
Screenshot with trace, boot dmesg and kernel config are attached.

Let me know if any more information is required.
