Hm, so I'm seeing boot crashes with the config attached:

Note that the config does not have NUMA_BALANCING enabled. With another 
config I also had a failed bootup due to the OOM killer kicking in. That 
didn't have NUMA_BALANCING enabled either.

Yet this all started today, after merging the NUMA patches.

Any ideas?

Thanks,
