hello,
doing a hyper-v 2016 build with gpu pass-through. close to completion (will prb post a full guide when i’m done!) but this gpu reset thing is killing me.
first off, i have two GPUs to test, an R9 270X, where this simply is a hardware bug, according to sources on the internet. so let’s ignore that one for now. i also have an AMD RX480, and i swear, in the last days of testing, no reset bug at all with this card! it worked just fine during countless VM reboots.
today i reinstalled everything from scratch, to get a clean system and document everything for the guide i want to post. and i can’t reboot my vm anymore! reinitialization bug - black screen, nothing happens (probably a BSOD but i can’t see it).
one thing i noticed during extensive testing, is that when the guest vm has the Microsoft default RX480 drivers installed (those from 2017-04), the bug doesn’t happen. once i install either the 2017-12-06 or 2018-01-12 original AMD drivers, the bug happens. i just wanted to leave this piece of info here, maybe it helps someone.
EDIT: here’s the guide if anyone cares
