--- Comment #1 from Mika Kuoppala <mika.kuoppala at intel.com> ---
This is kernel warn produced by:

if (WARN_ON((I915_READ(intel_dp->output_reg) & DP_PORT_EN) == 0))

So we are disabling an already disabled dp link.

Was the monitor you unplugged active and showing some stuff
or was it turned off or in sleep when you unplugged?
