However the fact it prints "ok" means it should have got past EDD detection (so I expect edd=off will make no difference) and the kernel is getting stuck somewhere else. If you look at where EDD is queried (query_edd ()): https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/a... it's just before changing video mode and going into protected mode, so most likely it's one of those things which is breaking. Also the EDD message is the last message printed through BIOS calls which is why it can appear to hang there even though the boot is continuing and perhaps stopping much later - you're just losing the later messages. You might want to try enabling more debug messages or (the ideal way) adding a serial console to enable you to see all kernel messages. What hardware is this? Something very old or unusual?
