Jamey's patch 3/9 might help. Otherwise if this is the first time you are trying it you may simply have encountered the reason that --real-mode is not the default. BIOS can get really strange after the kernel has been running. When I had that the default I only had around a 50% success rate or something like that. You might try booting kexec_test and see where that puts you. Eric
