Subject: [Bug 221918] New: amdgpu - Cannot find any crtc or sizes on AMD card with no crtc by design :-)
Date: Mon, 24 Aug 2026 17:45:45 +0000 [thread overview]
Message-ID: <bug-221918-2300@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=221918
Bug ID: 221918
Summary: amdgpu - Cannot find any crtc or sizes on AMD card
with no crtc by design :-)
Product: Drivers
Version: 2.5
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P3
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: kallisti5@unixzen.com
Regression: No
Getting a loop of "[drm] Cannot find any crtc or sizes" on an AMD Card with no
CRTC's by design (AMD Radeon Pro V620)
Since this is a compute-only GPU, the looping "[drm] Cannot find any crtc or
sizes" really isn't helpful and keeps the card in an incomplete state.
Kernel: 7.1.6-1-cachyos
Architecture: x86_64
