I've recently noticed that something weird is happening on my SMP machines.
Both machines are 2 x Xeon CPU with HT enabled. /proc/interrupts shows that
only CPU#0 is used which is very weird (and CPU#1 on one of the machines). I'm
running userspace irqbalance, too. I'm unable to alter affinity settings for
irqs - these are always the same as below.
Has anyone noticed such problems?
