Subject: BUG: using smp_processor_id() in preemptible [00000000] code:
 avahi-daemon:  caller is netif_rx

I get about 9 of these near the start of the system while userspace is

with a kernel from linux-next as of today.  The hardware is RHEL 5.5
with KVM:

commit: bbeecf185fe464ccd7ee97ce6d3646ad686995b4

I'm not sure what else to collect, give, test, try, show, debug or what
have you so let me know.  Attached is my full dmesg and config.
