--- Comment #4 from Maarten Lankhorst <bugs at mblankhorst.nl> ---
Interesting, difference between i915 fastset vs normal isn't much. Normal
appears to put the pipe in 10 bpp mode, and PP_CONTROL is slightly different.
TRANS_LINKM/N_EDP is probably slightly different as a result.

I don't think any of those differences matter much, so that leaves the question
why the short pulses..

Just curious what happens if you prevent DC from turning off? Adding
POWER_DOMAIN_PORT_DDI_A_IO to the power domain perhaps..
