Hi Mark,

Thanks a lot for the helpful comments.

Commit "c17fd15c00f Fix arc after r326347 broke various memory limit queries. 
Use UMA features rather than kmem arena size to determine available memory."
[1] is actually already present in the my build, so probably a different root
cause with the same symptom?

But talking about UMA, one thing I forgot to mention is that once I boot with
only 1 CPU it goes fine. Do you know if issue solved by fix [1] would also be
fine (would boot normally) if there is only one CPU?
