Agreed - but hangs rather than failing? > - What does the memory map look like?

Without capturing the memory map in full, it's hard to tell, except... > - What happens if you change AllocateMaxAddress to AllocateAnyPages in > efi_md_init()? I tried both switching AllocateMaxAddress to AllocateAnyPages, and also tried shifting EFI_ALLOCATE_MAX_ADDRESS by 4 bits (x16); same result in both cases, the same hang at the same place. -- Paul Ripke "Great minds discuss ideas, average minds discuss events, small minds discuss people." -- Disputed: Often attributed to Eleanor Roosevelt. 1948.
