| Subject: x86: Add quirk for Intel DG45ID board to avoid low memory corruption |
| |
| From: Alexey Fisher <bug-track@fisher-privat.net> |
| |
| commit 6aa542a694dc9ea4344a8a590d2628c33d1b9431 upstream. |
| |
| AMI BIOS with low memory corruption was found on Intel DG45ID |
| board (Bug 13710). Add this board to the blacklist - in the |
| (somewhat optimistic) hope of future boards/BIOSes from Intel |
| not having this bug. |
