  • Device: Ubiquiti EdgeRouter X (ER-X)
  • LEDE version: 17.01.2

We have several devices running, with 17.01.1 all is rock solid.
After upgrading to 17.01.2 we have problems with port connection interruption and sometimes kernel crashes.

Other people have similar experiences -> [[https://forum.lede-project.org/t/er-x-lan-port-connection-interruption/5709]]

guenti_r:

no changes on r4816.
maybe it is related to cpu-load, if adblock is processing and maxed out one core the disconnects appear.

note: random disconnects appear only on port 3

I have issue with frequently reconnecting too on Xiaomi Router 3G with trunk version. But it happens only on port 3, I reconnected my PC to port 2 and reconnections dissapeared

UPD: Oh, no, reconnections doesn't disappeared, it just happen lesser than before. And reason is uTorrent on my PC, when it opened and download/upload something reconnections happens much more often
