17.1 Legacy Series / WAN goes UP and DOWN constantly after disconnecting WAN and plugging back in

« on: July 27, 2017, 06:11:52 pm »

Hi guys,

I've had this issue for a while, but now have a few more facts. Basically I get in dmesg:

igb1: link state changed to DOWN
igb1: link state changed to UP
igb1: link state changed to DOWN
igb1: link state changed to UP
igb1: link state changed to DOWN
igb1: link state changed to UP
igb1: link state changed to DOWN
....
wash, rinse, repeat ...

repeating if either I unplug my WAN (ibg1) cable and then plug it back in, or my cable ISP goes offline then back online. I have to reboot the OPNsense to clear it.... :-/

The NIC is a igb1: <Intel(R) PRO/1000 Network Connection, Version - 2.5.3-k

on an APU2C4 mobo.

Connected to the WAN is an Arris cable modem in bridge mode.

I'm curious if others are having the same issue, especially with the APU mobos.

I've Googled around, and seems it also happens with some other network cards but I've seen no solid solution.

If anyone can help or run a test I'd be very grateful.

Best wishes to you all

16.7 Legacy Series / WAN going DOWN and UP

« on: December 18, 2016, 11:54:15 am »

Hi All,

OK bit of a long one perhaps, but I'll try to get as my details in here as possible in the hope you guys can advise:

I have an APU2c I bought from Appliance Shop EU, which has been running since July OPNsense. The LAN port is connected to a TP-Link gigabit switch, and the WAN is connected to an Arris cable modem in bridge mode.

The other day the internet started playing up, and while I thought it was my ISP, after digging around a little I realised it was actually the OPNsense box. I see the following in /var/log/system.log

This repeats constantly until a reboot. The odd thing is it can go anything from 5 minutes until 11 hours without failing, then suddenly again it begins.

To check it was not the ISP, I spoofed the OPNsense MAC address to a MacBook Pro and connected from the Arris directly to the MacBook Pro, and the connection is solid, no ping drops. If I then reattach the cable to the OPNsense it immediately continues sending the WAN interface UP and DOWN once again.

The only thing I do notice in the logs is a line like:

Dec 18 07:47:07 gw kernel: amdtemp0: <AMD CPU On-Die Thermal Sensors> on hostb5

I've tried swapping cables, rebooting the Arris, everything... I'm torn between if this is a HW or SW issue. I've looked at top output when it's been happening and not seen any problem processes.

So, your thoughts please guys?

All the best,
