Downgrade kernel 5.8* on Pine64+

Hi. I am getting a kernel Oops in the Pine64+   . . . .see below.  Kernel is 5.8.13-sunxi64. It was installed after a recent update.

I would like to drop back to the previous kernel if possible.

Does this seem like a reasonable search term for a suitable kernel?

Any ideas on searching and installing a previous kernel appreciated.

 

sudo apt-cache search kernel 5.8* | grep sunxi64

armbian-config -> system -> alternative kernels

Thanks for the suggestion. Kernel 5.8.10-sunxi64 is exhibiting the same problem. Not sure how this will impact things. No locking up so should I just go with it - ignore and carry on? It is used as a Tinker board more than anything. It is running docker and a few containers.

Allwinner A64 board are all experiencing some issues lately. Try kernel 5.4.y
