Hi Pier

The only thing I can tell that is, seems guest completely messed up... It ran into some non-code segment.

CR0.PE set(sorry for wrong decode before...), CR0.PG set. Guest in protected mode. But CR4 is wrong, at least CR4.PAE and CR4.VMXE should be set.

Seems like meaningless code...

Well, still don't know what the "checkpoint" done caused this... At least it seems more than a emulation bug.

Anybody else have idea?...
