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,
