    3.0 doesn't play nicely with multi-monitor setup for me. I'm running:
    ATI Technologies Inc Device 68f1 (ATI FirePro™ 2460 Multi-View) with 4 x DisplayPort screens.

    xrandr gives me:
    xrandr: cannot find crtc for output

    Switching back to 2.6.39 and everything works again just fine.
    Please report bug at: https://bugzilla.kernel.org/
    PS: I really hate that you have to register to 98765432 bugzillas, just to report the bugs you see. No matter kernel,mesa,gtk...etc. Can't there be one site, or something like OpenID?

      Lighting in Amnesia works now.

      I haven't had any major problems with any other games I've tried.

        disk io performance drop 3.0.0 kernel

        Currently I have experienced a substantial disk IO performance drop with the latest 3.0
        kernel
        on a 2 disk lvm most significantly on random write IO
        Has someone else experienced something similar on his box?

        Figures see below:
