They were meant to debug a problem in numa emulation that I fixed some time ago and sent to Andrew just a few days ago. http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=commit;h=c03cf0621ed5941f7a9c1e0a343d4df30dbfb7a1 You may want to try to checkout a full git tree to be sure it's not a collision with something else, at that point of the boot stage autonuma shouldn't run at all so it's unlikely related. Hillf just sent me a fix for large systems which I already committed, maybe that's your problem? http://git.kernel.org/?p=linux/kernel/git/andrea/aa.git;a=shortlog;h=refs/heads/autonuma I also added checks for cpu_online that are probably needed but those aren't visible yet but you don't need them to boot... If you want to extract the patch and all other patches to apply it hand, the simplest is to: git clone --reference linux -b autonuma git://git.kernel.org/pub/scm/linux/kernel/git/andrea/aa.git git diff origin/master origin/autonuma > x Or "git format-patch origin/master..origin/autonuma" -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
