I'll test with enable_msi=0 later.
Thanks.
FWIW, below is a patch I'm considering to merge (after testing, of course). Could you buys check it?

For reference, I'm seeing some of this too, and have asked for people to test with enable_msi=0 and/or power_save_controller=0. I'm waiting for replies from people with the hardware.
OK, good to know!
So far, I disabled the runtime PM up to PantherPoint in the patch. LynxPoint, Haswell and 3400 are still with runtime PM, as these were the platforms mostly tested for the feature.
