So ... it looks like this original issue (random crashes if this commit was made and the ROMs thing isn't patched) is a red herring.
For some time now, my Thunderbolt adapter (Lenovo 2nd-Gen TB dock) sometimes ... "acts up" on reboots/powerons with my laptop (Dell XPS 13 2-in-1) if I boot with it connected- I'll get random disconnects and/or lack of external video and/or its internal devices will drop offline. I suspect these crashes were related to the PCIe scribbling(?) somewhere(?) (even though I have IOMMU turned on). I can't track it down, and I think the issue may lie somewhere either with the Thunderbolt subsystem (my TB domain UUID gets regenerated on every boot and is always changing) or a bug in this Dell's BIOS (probably the likely culprit).
... in any case, I booted a fresh branch that does contain the commit in the Subject: line, and w/o Christoph's ROMs patch and as long as I don't boot with the TB adapter attached (or from a cold boot- SOMEtimes) it seems to work. So, my apologies for wasting everyone's time.
