looks like someone is triggering rebuild_sched_domains(), is something
poking cpusetfs files or flipping between sched_mc settings?

I remember someone mentioning that some distro's started setting
sched_mc_power_savings to '1' by default during boot. On a dual-core
laptop, this will not give any advantage.

I have to fix the code to not export this tunable, when we have only
socket in the system.

Dave, Is your distro also setting this tunable blindly during boot :(

(13:15:25:davej@vaio:~)$ cat /sys/devices/system/cpu/sched_mc_power_savings
0

So no, unless something set it to 1, and then back to 0.

A grep of etc shows up nothing in initscripts. Does hal or something
play with this?
