please give memtest86 a run. These sorts of bugs are very rare, and usually when something is broken here, it affects a number of people, but this is the only open bug we have like this.

You might still be hitting some weird corner-case, but ruling out bad hardware would be a good thing before we invest too much time into further debugging.
