Thanks for reporting and CCing me. First time I've heard of that function failing. The OP can just click continue or suppress and everything should work. To fix this, we just need to remove the two assertions and add a comment that this has been seen to fail on Vista SP2 with an ancient single-core Xeon. (Unfortunately that's just the generic name for server-grade CPU, but it looks like an early P4 with hyperthreading and nothing else.) Possibly Windows has decided not to use nor allow large pages on that CPU, but I don't see why they would do that.
