Linux handles eGPU hot-unplug just fine--it never crashed or glitched--but the Xorg instance using it and whatever was using it is now hung forever, which is... not optimal

to be fair to Linux, I believe the kernel interface *does* allow handling this, the proprietary nVidia driver doesn't seem to have any way to handle hot-unplug-while-in-use as it gets stuck in some lock… not that I complain, normal hot-unplug is hard enough and that works well

Yeeeah.. PCIe hotplugging works for some devices (e.g. ExpressCard USB and FireWire cards), but good luck getting Nvidia's giant turd of a kernel driver to cooperate with that.

no, it works completely IF nothing actually uses the GPU. I actually never got radeon to work with this Thunderbolt box.

Sure, I mean it works fine with USB/FW cards that are in use too. How does radeon not work? Hardware or software issues?

software. I plug it in, my :0 Xorg restarts, and if I start :8 Xorg with radeon and everything else turned off the system soft-hangs. it seems to be alive but the only input it responds to is the... power button, which shuts it down cleanly.

Ctrl+Alt+Fn, -novtswitch, nothing else works

SSH from another machine? Logs? Any indication as to what actually went wrong?

have not had a different machine to test; I got frustrated and just went back to nvidia, which never gave me this kinda shit :S

I also don't have any low-profile radeons; I'm thinking of getting a Kepler+ Quadro and just sticking to that

I dunno, I've had enough shit experiences with Nvidia's blob to write them off as an option in any future machines. At least with Radeon if something is broken I can fix it. :/ Maybe that's just a variant of stockholm syndrome from having ported the Radeon driver to PS4 though.
