Priority: medium Bug ID: 82714 Assignee: dri-devel@lists.freedesktop.org Summary: nouveau: fails to properly initialize GPU Severity: normal Classification: Unclassified OS: Linux (All) Reporter: bonbons67@internet.lu Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/other Product: DRI

In a system with dual GPU (Radeon HD 6550D [1002:9640] integrated in AMD APU + discrete GeForce 8600 GTS [10de:0400]) system boot fine and works as expected as long as no driver is attached to the Geforce.

Loading nvidia driver works mostly but suspend to RAM (S3) tends to fail.

Loading nouveau initialization is reported as successful but any attempt to use it ends in uninterruptible processed with nothing on screen.
