Subject: [Bug 208573] Black screen on boot if two displays plugged in with NAVI 10
Date: Mon, 10 Aug 2020 15:55:25 +0000 [thread overview]
Message-ID: <bug-208573-2300-k66VNzJj8k@https.bugzilla.kernel.org/> (raw)

--- Comment #9 from Thomas Langkamp (thomas.langkamp@medicalschool-hamburg.de) ---
Yes. With the new BIOS this is reproducible only with XMP enabled.
In the other bugreport I read about
amdgpu.ppfeaturemask=0xffffbffd
I just tried it. Until now this seems to fix it, even with XMP profile
enabled! I will report back if I get a black screen again.
As far as I know with 2 monitors attached the VRAM is always clocked
high, so it makes sense that disabling the VRAM power management through
this featuremask works around the issue. But surely a proper fix would
be appreciated.
