dmesg

The discrete graphics in my laptop (Intel HD 4000 + Radeon 7750M) doesn't initialize UVD successfully when it is powered on by DRI_PRIME.
Interestingly when the laptop is booted UVD is initialized.

My kernel is 3.14-rc3 from OpenSUSE head repository.
Userspace is from git.

Attached file is my dmesg. The errors at time 859.063821 correspond to the case when I ran glxgears with DRI_PRIME.

Can you attach your dmesg output with this patch applied?

dmesg after patch

Here you are.

PS Am I the only who sees the warning related to invalid certificate?

Alex, is there anything else I can help in fixing this bug?

dmesg

Kernel 3.14-rc5. The bug is still there. See attached dmesg.
Comment 6 Hohahiu 2014-04-05 22:28:06 UTC 
The bug is still present in Kernel 3.14.0.
Comment 7 Hohahiu 2014-06-13 00:10:37 UTC 
Somehow this bug is fixed for me in 3.15.0 kernel provided by OpenSUSE Head repository.
Since nobody else suffered from it I suspect it could be distro specific. So I mark it as "resolved worksforme" for now.
