You're not running master, it looks like.  I'd be interested to know if
this patch helps:

    drm/i915: Don't touch PORT_HOTPLUG_EN in intel_dp_detect()
    
    PORT_HOTPLUG_EN has allready been setup in i915_driver_irq_postinstall(),
    when intel_dp_detect() runs.
    
    Delete the DP[BCD]_HOTPLUG_INT_EN defines, they are not referenced anymore.
    
    I found this while searching for a fix for

I don't think it'll apply directly to 2.6.34 due to the
connector/encoder rework, but it should be straightforward to port.
