As the web page mentions, I tested downgrading the PCIe bandwith from GEN2 to GEN1 without success. But after playing with different BIOS options, what did the trick was limiting the power-saving C-states. If I select "C7" as the maximum C-state, the card fails as described. After limiting the maximum C-state to "C6", it has been working for a whole weekend.
