Earlier instances of the same problem. The 8 GiB barrier was because of the BIOS only issuing one 24-bit ATA command. I'm not sure how common will the new limit be in comparison. > I wonder what we should do about this: > - just always create a /boot partition when guided partitioning is used > - add some special cases, but how to reliably detect them? > - always ask if a separate /boot should be created (or probably better: > create separate recipes for that) > - only document the issues and how to solve them manually The problem with attempting to detect this bug, is that there's a chance our probe causes the BIOS to crash, or abort with fatal error. I think this would outweight the benefit. -- Robert Millan <GPLv2> I know my rights; I want my phone call! <DRM> What good is a phone call… if you are unable to speak?
