  • Hi

    I'm experiencing kernel bugcheck with DRM driver.

    The kernel output reports various reasons:

    1) wrong connector dpms state

    2) encoder->connectors_active not set

    3) crtc not active

    4) encoder's hw state doesn't match sw tracking

     

    I'm working with 3.14.3-rt5 on BayTrail module with my carrier board.

    For some reason I get this bugcheck without doing nothing special. The system just loads and waits but no more.

    On a different carrier board I don't get this bugcheck.

    What does this bugcheck means?

    I've attached the bugcheck output.

     

    Best regards,

    Tal
