There appears be a bug with newer yocto versions which results in kernels that crash with errors similar to:

This has been reported to Yocto in 2017 with seemingly no response here: https://lists.yoctoproject.org/pipermail/yocto/2017-November/039022.html

Hi, we have since moved to Yocto Sumo. Can you recheck now with the latest build from sources to see if this is still a problem?

splitice commented 6 years ago

@brdrcol has done a build recently based off master and it looks like this might be fixed with Sumo.

As we have not ported over all our SBCs supporting files / patches yet (and we don't have any other Allwinners) we can't say for sure however.
