This happens to me, lunar, kernel 2.6.0-20, Lenovo Carbon X1 gen 7, Dell monitor with built-in thunderbolt hub. Seems to happen more likely with big graphic updates (such as page change in Firefox).

(Monitor/hub works flawlessly with a dell laptop)

It starts with

[ 2713.078178] pcieport 0000:06:04.0: pciehp: Slot(4): Link Down
[ 2713.078183] pcieport 0000:06:04.0: pciehp: Slot(4): Card not present

and usually flaps up and down a few times before recovering.
