Subject[071/200] PCI: Disable MSI for MCP55 on P5N32-E SLI
2.6.34-stable review patch.  If anyone has any objections, please let me know.


From: Ben Hutchings <>

commit e4146bb9088c01c8b6e82be11f0c371f8aff023c upstream.

As reported in <>, 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.
