I haven't seen an actual kernel failure myself, this was reported by someone else. But it's easy enough to check with a simple Multiboot kernel that just outputs lower_mem/upper_mem and the mmap. For debugging and fixing I added some throw-away debug code to an existing kernel and compared the fixed version with the output when loaded by GRUB and it matches now. If we can have a real test case for this somewhere, I can write a small kernel to do the check. Not sure where it would fit though - probably kvm-unittests is the closest, even though the test wouldn't really have anything to do with KVM. > I'll apply this after a day or so when others have had a chance to review. Sounds good, thanks. Kevin
