We are still hitting problems with MSI (and probably mmconfig) with kernel 2.6.22: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=249469 Should we just go back to disabling these by default?

And there are quirks in there now, I guess the list just isn''t complete (and probably never can be.)

Weren''t there other newer devices that need MSI on ? Some of the infiniband stuff maybe? As painful as it is, additional quirks would be the best all-round solution I think.

Might be useful to do that as a comparison too. If a bug goes away on FC6, and sticks around on later releases, whilst we''re on the same codebase, we should be able to spot MSI failures a little easier. Dave -- http://www.codemonkey.org.uk
