That didn't work, but it seems this was just my config, the same config worked on older kernels but I am not motivated enough to figure out what I actually did enable which fixed this. But just for the record config which did not work: http://bombadil.infradead.org/~mcgrof/configs/2010/config-issue/config-= old.txt config which worked: http://bombadil.infradead.org/~mcgrof/configs/2010/config-issue/config.= txt The diff: http://bombadil.infradead.org/~mcgrof/configs/2010/config-issue/diff-34= -35.patch Luis -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
