Created attachment 69423 [details] AMD SUMO GPU lockup when I launch Unigine Heaven 3 GPU lockup happen for me while launching any heavy 3D application on Radeon HD 6620G. For example GPU lockup 100% reproducible when I launch Unigine Heaven 3 (dmesg attached). It also may happen in web-browser, if browser use rendering hardware acceleration (for example Firefox with enabled "layers.acceleration.force-enabled" option). Lockup is not reproducible when I launch same applications on discrete Radeon HD 6650M GPU using DRI_PRIME feature, so I guess my issue related to AMD SUMO GPU's (or maybe to more APU's). Software: Kubuntu 12.10 x86_64 updated from Xorg Edgers PPA. Linux 3.7rc3. With Linux 3.5 and 3.6 is also reproducible, Mesa: 9.1~git20121029.00e6819e libdrm-radeon1: git20121025.bc494b31 xserver-xorg-video-radeon: git20120928.e8cb0b72 xserver-xorg-core: 1.13.0+git20120920.70e57668 KDE 4.9.2, desktop effects enabled. Hardware: Acer Aspire 7560G laptop, BIOS 2.04, AMD APU A8-3500M with integrated Radeon HD 6620G (SUMO) Discrete AMD Radeon HD 6650M (TURKS)
Can you try mesa 8.0.x? This might be a duplicate of bug 56405. If 8.0.x works, can you bisect?
> This might be a duplicate of bug 56405. Probably. If my issue is still reproducible when the bug 56405 will be fixed, I'll reopen this bugreport. > Can you try mesa 8.0.x? With Mesa 8.0.2 (Kubuntu 12.04.1 x86_64 LiveCD) there is no GPU lockup in Unigine Heaven 3. > If 8.0.x works, can you bisect? I'm afraid I can't.
