That's kinda neat.  It's the same problem (and the same random

It just seems so odd that 3 bits could get flipped like that a second

yeah was thinking the same thing.. thing is, is this happened when I was fixing a typo in the kernel and just doing a git commit -s -a (then the below appeared) reported to lkml another issue with git maybe this is what's hitting(guess Ill update to the current for git, then see if anything like this appears, as well as the other report..

thanks for taking a look!!

What Linux Distro have you installed on your MacBookPro2?

it seems, you are not using your standard kernel shipped with your Linux
