| Subject: PCI: Disable MSI for MCP55 on P5N32-E SLI |
| |
| From: Ben Hutchings <ben@decadent.org.uk> |
| |
| commit e4146bb9088c01c8b6e82be11f0c371f8aff023c upstream. |
| |
| As reported in <http://bugs.debian.org/552299>, MSI appears to be |
| broken for this on-board device. We already have a quirk for the |
| P5N32-SLI Premium; extend it to cover both variants of the board. |
