It might all be down to some very dodgy looking PCIe cabling.
The board doesn't plug directly into a PCIe socket, but it connected by two 'SATA' cables connected header board plugged into the PCIe socket.

Sounds like my kind of hardware setup :) (I use PCIe to SMA breakout cables from SAMTEC)
Can you try running a transceiver toolkit test? You do not need a PRBS pattern generator at the other end, just traffic ... I'm pretty sure you can run TTK over a valid PCIe link, but I have not tried to do that.

And the 40 minute build times don't help the rate of debugging (on a i7 with 8GB memory running Ubuntu).

Ha! I hear you on that one ... I script my long compiles so that I can walk away while my machine builds multiple designs ... but that does not help when debugging!
