You can see that in the gist: "NVME polled command failed to complete with= in 1s" Same as before (with straight ECAM)=2E Looks like straight ECAM *is* supposed to work, after all (with limitation= s on bifurcation or something, I've heard)=2E The code I'm porting from Net= BSD does use that same ECAM space when touching non-0 busses=2E Whoops, I might've been working on increasing features instead of fixing b= ugs=2E=2E :D It's odd that what's failing is just polling I/O with the devices, and aft= er successful reads=2E Does that smell like cache issues or something?
