Subject: [PATCH] pci: disable MSI on VIA K8M800
|
||
|
|
References: bnc#599508
|
||
|
|
Patch-Mainline: Pending for 2.6.35 and -stable
|
||
|
|
|
||
|
|
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.
