The last bit out of my serial console looked like: --- Booting Node 0, Processors #1 smpboot cpu 1: start_ip =3D 98000 cpu 1 node 0 cpu 1 apicid 2 node 0 Pid: 0, comm: swapper/1 Not tainted 3.3.0-rc7-00048-g762ad8a-dirty #32 Call Trace: [] numa_set_node+0x50/0x6a [] init_intel+0x13c/0x232 [] ? get_cpu_cap+0xa3/0xa7 [] identify_cpu+0x240/0x347 [] identify_secondary_cpu+0x14/0x1b [] smp_store_cpu_info+0x3c/0x3e [] start_secondary+0x109/0x21e numa cpu 1 node 0 NMI watchdog enabled, takes one hw-pmu counter. #2 smpboot cpu 2: start_ip =3D 98000 cpu 2 node 0 cpu 2 apicid 4 node 0 Pid: 0, comm: swapper/2 Not tainted 3.3.0-rc7-00048-g762ad8a-dirty #32 Call Trace: [] numa_set_node+0x50/0x6a [] init_intel+0x13c/0x232 [] ? get_cpu_cap+0xa3/0xa7 [] identify_cpu+0x240/0x347 [] identify_secondary_cpu+0x14/0x1b [] smp_store_cpu_info+0x3c/0x3e [] start_secondary+0x109/0x21e numa cpu 2 node 0 NMI -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
