Hmm, that should have been fixed with this pull request: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e92b99ae8216dec2566711dae0a9b7b47591e315 Let me know if you have that, and if so, please send me your config. Oh, and make sure that you have the latest selftests running too. Thanks, -- Steve
