Regarding statement: "If I do not access the grub2 menu, I can login to X and everything is fine." No, not at all. My tests yesterday were all without accessing the grbu menu. Ie, without accessing grub at any time, booting into 3.2.0-20.33-generic-pae I was able to login without corruption one time out of 3 with a cold reboot and 1 time out of 7 with a warm. (This is why I removed grub from the description).
