Hi Andre, I also have upgraded to 16.10, hoping for the bug to be fixed, as everything seemed to go smooth until kernel 4.7. However, I still got kernel panics. In short, kernel 4.5 didn't have the bug: it was introduced by the backport Canonical made of amdgpu to 4.4. However the same bug, or a

Maybe we should mark it as confirmed now that Yuri bisected the kernel in the other bug? However I still think we should just put some test to check whether the pointer is NULL, we already have the stacktrace. Maybe I can try to patch it out when I get some spare time. -- You received this bug

Will bisect work in this case? I had understood from the release notes that most of the 4.5-vanilla's amdgpu was backported to Ubuntu's 4.4 kernel. As I commented in the first message, 4.5.0 does not present the NULL ptr dereference, so it would not really be a bisect from 4.4 to 4.6-rc7, but

Behavior with 4.6.0-040600rc7-generic appears to be even saner than with 4.5.0-050400, although the AMD GPU is still not usable ("DRI_PRIME=1 glxgears" opens a black window). Only after reporting this bug, I found that 4.5.0-050400 presented issues with sound output in the HDMI port (sound output
