Hello,
I recently upgraded my thinkpad x220 laptop from 11.2 to 12.0 and noticed that the em0 interface stopped working properly.
It works correctly after rebooting, but hangs after a suspend/resume cycle. Restarting the netif service does not help. Sometimes it gets an IP but no traffic after that.
This interface worked perfectly before, under FreeBSD 11.2.
The wireless interface works flawlessly though.
There is also a message
I also read that there were many changes in the intel driver in version 12.0. Maybe it's now buggy?
Does anyone else experience this?

There is also a message
sendmsg on em0: No buffer space available
which I don't know if it's related or not.I also read that there were many changes in the intel driver in version 12.0. Maybe it's now buggy?
