Qualcomm Fast Path For LEDE

Yesterday evening it happened again (after 1.5 days): lan connection was dropped. (reboot solved the problem again)
This time I spent a little time with it:

  • wifi iface worked ok (that's how I ssh-d in)
  • pppoe wan connection was also dropped (not showing up on the list of ifconfig, but eth0 was there)
  • brlan, wifi and eth1 were both showing up on the list of ifconfig
    So it seems all the wired connections stopped working for some reason but not wireless.

Any ideas?
(I have to say that the image is my compilation according to your instruction, and I didn't have any issues.)
Thanks
