The bridge itself is flaky and doesn't handle interrupts properly all of the time. About the only thing we could do to limit scope even more is to only enable the quirk if there is a device actually behind the bridge. That will help people that have the broken hardware, but aren't really using it. Most people have something behind the bridge though. There are two alternatives here. Drop the patch entirely, or come up with a boot parameter that can be passed to disable it. If we drop it and old method of IRQs is used, it will basically disable the interrupt permanently for that boot. That might sound OK, but if the IRQ is shared it can make people's computer useless until it's rebooted. The boot parameter could be helpful, but people would have to know about it before they can pass it in. Opinions on which to use? To be honest, I'm leaning more and more towards dropping it entirely. josh _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
