DM365 kernel upgrade from 2.6.37 to 4.0.1

Hi all,

we are currently using the IPNC 5.1 rdk (PSP 3.21.00.04) for our application. The kernel used is 2.6.37, we would like to upgrade the kernel to 4.0.1 but we are running into some issues.

When we enable the capture, we get an "unexpected interrupt trap at vector 00" error.

We also tried to check the encoding engine by using a file as an input. In this case the encoder seems to lock up and we get a "sched: RT throttling activated" error.

My questions are:

Has anybody successfully upgraded the kernel 2.6.37 to a 3.x or 4.x kernel? If so what did it take to make it happen? Is it even possible?

Thanks.
