Bug ID: 155141 Summary: [KMS] Artifacts with OpenSource Radeon driver Product: Drivers Version: 2.5 Kernel Version: 4.7 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: tinctura.ginseng@gmail.com Regression: No
OS: Arch Linux Hardware: Notebook ASUS F8Vr, CPU Intel Core 2 Duo P8400 2.26GHz, 4 GB RAM, Mobility Radeon HD 3470 (RV620)
After update kernel from 4.6.4 to 4.7 I found artifacts when KMS activated - blue dots drop down in console and graphics mode. Downgrade to 4.6.4 - not found any artifacts. Upgrade to 4.7.1 and 4.7.2 - artifacts is found. When I disable KMS with 'nomodeset' kernel parameter the artifacts disappear.
