I am using 2.6.35 kernel with my X1300 card and got this output in dmesg: ... [ 2.705641] failed to evaluate ATIF got AE_BAD_PARAMETER [ 2.705644] radeon 0000:01:00.0: Error during ACPI methods call ... Don't know if this a kernel bug or buggy BIOS (ACPI ...). Got a Dell OptiPlex 755 with BIOS A17. Maybe someone with more knowledge can give some hints if this is a serious error or a "harmless" warning.
Is this a regression? Was 2.6.34 OK?
This is not a bug. Not all systems have the ATIF table. "Fixed" in: http://git.kernel.org/?p=linux/kernel/git/airlied/drm-2.6.git;a=commitdiff;h=dc77de12dde95c8da39e4c417eb70c7d445cf84b

It's a HD 4890 card, and the kernel is x86_64. So am I seeing a bug? Presumably with the about patch, my card really *does* have an ATIF table for me to see this message.
