The change to /sys/src/9/pc/apic.c made on 13 July makes my system
(dual-processor atom) crash soon after the ethernet (rtl8169) is
enabled.  Symptom: either a silent hang, or "panic: freeb: ref -1"
called from etheriq (simultaneously on both cpus).

Is one interrupt being dispatched to two cpus, I wonder?
