Hello,
AFAIK, nobody mentioned that the current snapshots for the ER-X-SFP make the device unusable because it hangs most of the time. I suspect that it might have something to do with the support of the MT7530, DSA and the SFP port. However, I am unable to prove where the problem stems from (given that the device hangs most of the time without displaying any issue as far as I can tell).

Feel free to tell me what details I should show here. For the record, I tried the three last snapshots and while compiling my own (even the Target Profile "Ubiquiti EdgeRouter X SFP" available on buildroot).
Edit: I noticed that this behaviour disappeared when I remove the cable on eth0. I do not know why, everything is back to normal and you can finally access your device through ssh without having the device hanging and waiting to type commands. I am going to see what could cause that starting to see if the uci defaults are the same from 19.07.
