By and large, the EFI runtime Time services just don't work very well on x86. Just because they work sometimes, doesn't actually mean it's a good idea to use them.

I have vague recollections of someone working on that. -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
