--- Comment #11 from Imre Deak <imre.deak at intel.com> ---
Unfortunately the boot log is truncated. There are a few other issues before
the first visible DDI_IO_C power well problem, possibly we need to treat them
separately:

<3>[   12.927020] [drm:gen8_de_irq_handler [i915]] *ERROR* The master control
interrupt lied (DE PIPE)!

<4>[   13.365757] plane 1A assertion failure (expected off, current on)

<3>[   14.312254] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun
