The last drivers/w1 change went in before v3.14-rc1, so if it is something in the w1 code, it has either been there or something else in the rest of the kernel changed to expose it. I'm using the ds2490 USB w1 dongle, I didn't see that problem when enabling lock debugging on 3.14.0-rc5+ which includes some changes I'm working on. https://github.com/dfries/linux.git w1_rework -- David Fries <da...@fries.net> PGP pub CB1EE8F0 http://fries.net/~david/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
