ISTR seeing some mention of problems with X & MCE messages on Sandy Bridge.  The first thing to try is reverting this patch in your kernel: linux-2.6 commit ccab5c82759e2ace74b2e84f82d1e0eedd932571.

Some of the Dell R910 laptops had this weird error too.  It was caused by some bogus MCEs being kicked during C1E and C-state transitions BUT ... that was a different processor (Westmere or Nehalem IIRC).

In any case this isn't a critical situation -- your laptop keeps running and is warning you that it thinks something is wrong.  Can you try disabling C1E and C-state transitions in your BIOS?
