Unfortunately, there isn't really anything to go on here. I don't see any network-related error messages in the attached dmesg, so whatever issue you're encountering on 12 doesn't seem to exist on 11.2. You might want to try using HEAD (like a snapshot that's post 1/30), since there have been a couple fixes to the em driver in the past couple days. (In reply to kaan from comment #0) Do you still have this hardware? I'd like to see pciconf -lv for the em devices, and have you retest on 12.2-RELEASE or 13.0-RELEASE. Yes, we still use this hardware, I updated it to 11.4 and I plan to migrate to version 13 but because this is a rather critical network node, we will carry out migration in the summer.
This is the pciconf -lv output for all devices:

Created attachment 201549 [details] dmesg from 11.2 After upgrade from 11.2 to 12.0 my network stop to work. Network cards get addresses but data exchange does not occur. I tried a clean install, but the situation has not changed. I have only 11.2 dmseg, because had to rollback quickly.
