I think the basic problem is that Yinghai's patch broke your system, and this is a regression between 2.6.33 and 2.6.34. We could use a quirk like yours (which looks fine, BTW) to cover up this regression, but I don't like that approach because other machines are probably affected by the same issue, and we'd have to find and fix them one-by-one. I think it'd be better to figure out the problem with 3e3da00c01d and fix or revert it. I said earlier that I wasn't in favor of just reverting it, and I still don't like that option because it will likely break something. But Yinghai didn't supply any details about the system that 3e3da00c01d fixed, so I don't know how to fix things so both that system and yours work. I assume that 2.6.34 with 3e3da00c01d reverted will work fine even without "pci=use_crs". Can you try that and attach the dmesg log? -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
