This should have been fixed in the second patch:
02/28 ("sched: Several fixes for cache aware scheduling")that the LLC 
sched domain could be NULL and we should skip the
NULL LLC sched domain.

It might be more applicable to test with the whole patch set.
As this is a RFC version and we will create a formal one with
the fixes integrated into the 01/28 patch, after the issues
have been addressed.

thanks,
Chenyu
