andi,
please refer the patch, it will move cpu_set(, cpu_callin_map) from
smi_callin to start_secondary.
This patch fixes an apparent race / lockup on our 2-way dual cores (when
applied against 2.6.12.3). The machine was locking up after
"Initializing CPU#2".
The real solution for this issue is the smp_call_function_single patch from Eric
that I reposted yesterday. Yh's patch just changed the timing slightly.
Indeed.
I had a report here that the smp_call_function_single patch wasn't
fixing our problem. I just tried it myself and it appears to also fix
the problem.
Thanks,
Mike Waychison
