It's possible that the bug is caused by buggy firmware, but if so it's NOT restricted to Sandy Bridge systems. My own computer uses an Intel DG43NB motherboard (Intel G43 Express chipset with AMI EFI 2.00) with a Celeron E3300 CPU, which predates Sandy Bridge by quite a while. As noted earlier, I've got the problem when rebooting, although shutdown is fine on my system.
