Thanks for providing the data. All looks normal there.
Just for clarification. Did this happen exactly once, or did it just not
happen again after you plugged in a serial cable?
One thing you might try is to disable irqbalanced when the machine is up
and then stress the affinity setter mechanism with scripting.
Something like
while true; do
for I in {0..3}; do echo $I > /proc/irq/$IRQ/smp_affinity_list; done
done
might be able to trigger it. But don't ask me which interrupt was involved,
so you have to iterate through the ones which are MSI based.
'cat /proc/interrupt | grep MSI' will tell you.
Thanks,
