1. Why does VMware need max_cstate=1 to load quickly? It should not, and the fact that it does means that something somewhere is seriously broken.
2. Why does the "max_csate=1" workaround help only on the dual-core boxes, while the single-core boxes still fail to load quickly?
I'm glad that we deleted run-time access to max_cstate -- it seems to have exposed a real bug that needs fixing and has gone unreported until now.
Indeed, when the real bug is fixed, I propose that we again move to delete max_cstate as a run-time API.
