Hi,
Here's an interesting issue, apparently Core i5 and i7 have problems after resume from suspend/standby.
I wonder whom at Intel I should let know about that.

Maybe it might also be useful to bring someone from Intel in on this. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
