E.g. one of them updating the CPU (not GPU!) microcode at boot, but the other one not.
Nope i tried both with/without updating CPU microcode, tried also distro kernel from experimental that is linux-image-3.17-rc5-686-pae currently... in all cases corruption is still there.
Well to reproduce it someone must install 32bit OS :)
