I'm also affected by this. Ubuntu is unusable on my i5775 and hangs with MCE constantly.
I'm very surprised that intel has not addressed this yet. Usually intel support for Linux support is excellent..
Many others are reporting the same issue, e.g. https://bbs.archlinux.org/viewtopic.php?id=201194
I'm also affected by this on Fedora 23.
joe_intel no, the reason why the person in that thread was reporting that Fedora worked okay is because they were using an older version. The latest version is most certainly having the same issue.
