  • Is anyone else having Radeon / KMS problems with 3.12.x?

    Hi,

    I've just tried to boot 3.12.2 with my HD4890, and the screen went dark as soon as the radeon kernel module loaded. Is there something "special" I need to enable in the kernel .config that I've missed please? Or is this a bug? (I have raised Kernel bug #66241 in Bugzilla already).

    There's also this thread on the linux-kernel mailing list, which looks familiar. But there's no follow-up.

    There is no special build option i know of. I did have something similar, but i had only blank VTs, X was fine and it was related to missing framebuffer drivers or something (didnt really thought of it again since i ticked some additional options there in the config).
    Do you have dpm enabled? If yes, try without it, if no try with it.

      I have tried both with and without dpm, without success. Similarly both with and without aspm.
