This looks like a duplicate of http://bugzilla.kernel.org/show_bug.cgi?id=13940

There's a patch in that bug that is upstream already:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=15b812f1d0a5ca8f5efe7f5882f468af10682ca8

Please try booting 2.6.31 with "pci=use_crs" and report the result.

If possible, please also try booting an upstream kernel containing
the patch above (without "pci=use_crs") and report that result, too.

Ping!  A.G., have you had a chance to try this out?
