The bottom commit (3003) passed and the top commit (3000) failed, so the 
problem is one of the patches in between. We are now about to test kernel 3004 
in the middle.

You can find kernel 3004 here:

https://kernel.ubuntu.com/~kmously/kernel-kmously-721de44-fWzO/


Please ensure you are running version -3004. Thank you
