Intel Pro 1000 (em0) - sched_ithd: stray interrupt 22 on cpuX

Looks like em0's interrupts are broadcasted to all CPUs. Please add
following to /boot/loader.conf:
dev.em.0.msi.enable=1
Hopefully it should fix your issue. Though there is an erratum for
enabling MSI on 82571, it should work for normal use.
What do you mean by "stops responding for several dozen seconds in the
loop"? Do you mean polling does not work? Or something else?
Thanks,
sephe
