Peter,
What's your opinion about the patch? We hit it when enabling Medfield Android
mobile.
This patch would put AP to a loop.
Another method to fix it is just to enlarge the wait time, for example, from
2HZ to 10HZ.
Hmm... and I presume running with preemption disabled doesn't work for
hotplug (not that this is a hotplug situation)...
2 seconds is a *long* time, but I guess there isn't really nay harm in
making it 10 seconds in the sense that the system is basically dead at
that point...
tglx - you have been looking at the CPU startup lately, any opinions?
