4.4.x kernel (only) gives pcieport 0000:00:1c.4: AER: Corrected error received: id=00e4

Howdy,

I just upgraded my laptop to a Lenovo thinkpad P70 (skylake), moved my linux
image (4.4.1 kernel), and I'm pseudo-randomly getting these:

pcieport 0000:00:1c.4: AER: Corrected error received: id=00e4

They did not seem to be happening with 4.3.3 kernel.
With 4.4.1, I've had a boot where I got so many of those that the machine was unusable.
Other times, it happens a bit, and stops.
My last boot, it didn't happen at all.

Sadly, I have no idea what they mean, what I should do about them, and
why they only seem to be happening with 4.4.1 and not older kernels.

Can someone offer some suggestions?
