Which revision are you testing, and do you have any local changes?

I built a plain -current USB stick image a while back and had no
trouble, when using the HDMI output. I don't recall the revision at
the moment, but will try again soon. Serial console won't work because
the UARTs are not quite 16550-compatible.

We do need a GetMemoryMap() / ExitBootServices() retry though.
