The second half of the bug looks like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/766970 (My experience is filed under a duplicate as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/910041)
I also saw fsck fixing some issues at boot before I saw the oops on mount. But I had attributed it to hdd errors or something.
