You have unsupported kernels, this is why it is important to not cut down information you give (like you did with inxi).
Install supported kernel.
mhwd-kernel -i linux515
Reboot, and remove the unsupported kernels
mhwd-kernel -r linux513
mhwd-kernel -r linux514
Before doing that maybe give full list of kernels used with mhwd-kernel -li so we can have a better view. Also a full inxi -Fazy
