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,

Can you try mesa 8.0.x?  This might be a duplicate of bug 56405.  If 8.0.x works, can you bisect?

Probably. If my issue is still reproducible when the bug 56405 will be fixed, I'll reopen this bugreport.

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.
