And again, Hi all, I've been battling with my "parrot" repeater crashing, using the Banana Pi and Fedora 29 Linux.
So I'm trialling a Banana Pi M2 Berry running Ubuntu 16.04 with an old old kernel 3.10 series. There are bugs, bad bugs with the latest AHCI-SUNXI and other laptop AHCI (SATA) drivers. It's all about Power Management. It seems kernels before 4.16.xx are OK. I've been battling with this for months!!!! I can't deploy an unreliable system!!!!
