Some machines don't boot unless passed pci=nocrs.
(See https://bugzilla.redhat.com/show_bug.cgi?id=770308 for details of
one report. Waiting on dmidecode output for others).

Currently there is a DMI whitelist, even though the default is on.

This patch extends that dmi list to add a blacklist to automatically apply disable it when necessary.

This is a band-aid, and we'll have to extend the blacklist for other machines, but it's the best we have right now, so I think it's the right thing to do.

It's probably the same as
https://bugzilla.kernel.org/show_bug.cgi?id=31602 (Dell 1546) and

There's at least one more dell (Seems that entire 'studio' product line is affected) that I'm waiting on DMI data from.
Also a thinkpad that I have a patch pending for.

I think we should drop the Dell 1536 blacklist entry from this patch (adding set_nouse_crs() itself is fine and may be needed for other machines).

The patches here: https://lkml.org/lkml/2012/1/5/402 should cover the Dell 1536 issue as well as the Dell 1546 and any others with the same BIOS defect.

Ok just did some patch mangling in linux-next. After a quick build test I'll push it out and you guys can make sure you're happy with things.

Looks like this depends on a Thinkpad patch you haven't sent yet; did you mean to?

I've fixed it up by hand and applied both the 1536 and 1557 patches to my for-linus branch. I'll see if Linus wants to take it before he releases (doubtful, but it would be nice if these machines just worked with the new kernel).

Thanks,

Btw., should we perhaps match on all things 'Studio*'? For these two systems i'm sure there's 20 other models we have not covered yet ...

I think we should hold off on merging this patch upstream. We don't understand the root cause yet, and I haven't seen any evidence that setting "pci=nocrs" actually makes a difference in PCI resource allocation (https://bugzilla.redhat.com/show_bug.cgi?id=769657#c27)
