4 days after update (v3 -> v5) WAN port was disabled.
OS version 5.1.10, I ran the migration tool from version 3 4 days ago. I use DSL router in bridge mode to connect to the Internet. I never used an SFP module (never even held in my hand :). Today after one restart while configuring Omnia my network went offline. I do not have a clue why.
I noticed then that the WAN interface in Luci did not have a device/interface assigned. Also, the WAN LED was lit regardless of whether the cable was plugged in or not. After following up on the information that WAN port name was changed to "eth2", I found a suspect:
root@turris:~# ls -l /boot
-rw-r--r-- 1 root root 18773 Mar 4 01:25 armada-385-turris-omnia-phy.dtb
-rw-r--r-- 1 root root 18809 Mar 4 01:25 armada-385-turris-omnia-sfp.dtb
-rw-r--r-- 1 root root 1199 Mar 4 01:25 boot.scr
lrwxrwxrwx 1 root root 31 Mar 14 17:56 dtb -> armada-385-turris-omnia-sfp.dtb
-rwxr-xr-x 1 root root 3351944 Mar 4 01:25 zImage
this fixed it:
root@turris:~# ln -sf armada-385-turris-omnia-phy.dtb /boot/dtb
root@turris:~# ls -l /boot
-rw-r--r-- 1 root root 18773 Mar 4 01:25 armada-385-turris-omnia-phy.dtb
-rw-r--r-- 1 root root 18809 Mar 4 01:25 armada-385-turris-omnia-sfp.dtb
-rw-r--r-- 1 root root 1199 Mar 4 01:25 boot.scr
lrwxrwxrwx 1 root root 31 Mar 14 19:30 dtb -> armada-385-turris-omnia-phy.dtb
-rwxr-xr-x 1 root root 3351944 Mar 4 01:25 zImage
I think there must have been at least few other reboots before the incident but I am not 100% sure. Earlier today I did change wifi setting as well as used the "Reset Wi-Fi Settings" button in reForis, I aso launched few migrated LXC containers for the first time.
Please let me know if I can provide any useful information.
