I think that try to load the capemaneger but in the kernel 3.14 upwards there is no capemaneger, how I proceed in this case?

I have never tried on 3.14 but I think now it's time to work on it. I will update in a few days after trying on my board.

Thank you, I went back to 3.8 but I will be watching for news. Thank you for your response.

adityapatadia commented 9 years ago

Hi, the latest image I tried on BB has 3.8 kernel. Is there a compelling reason to move to 3.14? If yes, then I will also install it and upgrade this library to support it.

brilvio commented 9 years ago

I don't think right now that there is a reason, because now I have 4 BB with 3.8 kernel running 24/7 and I don't have a problem, if I discover a problem because of the version of the kernel I will be in touch.

adityapatadia commented 9 years ago

And those BB use OBS? That's really nice to hear. Actually OBS can support 3.14 without much modification. I am not doing it since official images are still at 3.8. Let's see what we can do in future. Closing it for now.

brilvio commented 9 years ago

Yes those BB are using OBS, thank you.
