I do have VGA. Never used it.

Will do.

At first suspend but not at subsequent suspends so far, with 3.17.
I think I have two suspend bugs:
1) intel_display.c: assert_can_disable_lcpll as seen with 3.15 and 3.17
2) intel_pm.c: intel_display_power_put as seen with 3.16 and might be the lock
Maybe #2 also turns up eventually with 3.17. We'll see.</pre>
