Thank you for your detailed explanation in the patch. > It does not > fix any lockup/crash/... I know. I was surprised that my patch fixed something else, but now we know that it didn't. It's better when patches don't have unexpected effects even if the effects are positive :) > And your PCI-BAR adjustment doesn't change > anything either, sorry. I simply tried another approach to pacify the resource checker. However, there is some difference. nvidiafb cannot access the resources if IORESOURCE_BUSY is used. It's not that it matters for me. nvidiafb fails on my hardware anyway and I don't need it when I already have simplefb and nouveau. But I think we should have a closer look why it fails and what other drivers may fail. -- Regards, Pavel Roskin
