| Subject: PCI: disable MSI on VIA K8M800 |
| |
| From: Tejun Heo <tj@kernel.org> |
| |
| commit 549e15611b4ac1de51ef0e0a79c2704f50a638a2 upstream. |
| |
| MSI delivery from on-board ahci controller doesn't work on K8M800. At |
| this point, it's unclear whether the culprit is with the ahci |
| controller or the host bridge. Given the track record and considering |
| the rather minimal impact of MSI, disabling it seems reasonable. |
