Bingo. Swapped only the RAM modules, and the corruption moved to the other system, and the original one is now fine.
I have no clue why disabling rc6 would hide the problem. (Happy to do further testing along these lines if you wish). I'll run some memory tests to be certain, but am going to assume it is simply bad or incompatible memory. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/954660 Title: Intel DH67GD board w/ i5-2405S cpu fails to boot with rc6 enabled To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/954660/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
