Hi, Dan

did you try setup forsed 8MB value on window->phys?

Actually, I tried to force it at 4MB starting at 0xff800000 since it made much sense looking at the e820 map. Or maybe I misunderstood something. It crashed with this:

I can dump here the disassembly of cfi_probe_chip if it's interesting...
