MBP16: IntelAccelerator prodding blockFenceInterrupt

[dingobiatch]

I'm getting random 2-5 second hangs in Finder and Chrome, which seem to correspond with these messages in Console:

"fault 15:10:31.499686-0800 kernel void IOAccelFenceMachine::fence_timeout(IOTimerEventSource *): IntelAccelerator prodding blockFenceInterrupt"

Tons of these messages show up. I can't figure out what I'm doing... I have a few tabs open in Chrome, but it's nothing crazy and none of the websites are anything special. Any ideas?

seems to be a common problem:
