Panic hit with Anker adapter
I have experienced this problem, too, on a Dell XPS laptop (manufactured late 2019) which has no ethernet socket and thus forces me to use a USB2LAN adapter. I've tried out two: The Dell one that came with the laptop and an Anker one that I've been using without problems e.g. when playing with my Pinebook and FreeBSD. Both are directly (no HUB or such) attached with traditional USB plugs (not USB-C). I've uploaded dmesgs for system starts with either adapter attached. I've observed that networking generally does work. After installing 13.0, I had trouble running freebsd-update. It started to download files but then the system would lose connection (state for ue0 changes from active to no carrier. Removing the network plug and putting it back didn't help but pulling out the USB connector and reattaching it did. However the same thing happened if I tried to run freebsd-update again. Updating briefly worked with the other (Anker) adapter, so I continued building my system. I was able to zfs send over 100GB to the laptop without the network having any issue, install a lot of packages for desktop use and so on. But when I tried to use Ansible to provision another machine from the XPS, network connection would immediately break. So I decided to clone the FreeBSD source and update to 14-CURRENT to see if it happens there, too. Unfortunately cloning a git repo triggers the same problem. Therefore I cloned it on another machine and scp'd it over. System is running 14-CURRENT now and the situation has improved (cloning seems to work now) and Ansible can do a few tasks instead of losing connection immediately, but ultimately it still fails after a moment. This is all a bit weird. I know that the Anker one works just fine with other hardware and I briefly tested the Dell one on another laptop as well without any problems. And since 14-CURRENT behavior definitely is different from 13.0, some related work seems to have been done. A former co-worker used the machine with Ubuntu installed and I don't know of any network issues. I hope this helps with identifying what the actual problem is. I'd be happy to answer questions or provide additional info. I'm also getting unstable connections with two Realtek Ethernet USB-C adapters. The first one is inside a Dell W19TB docking station. The second one is a standalone adapter. The laptop (a Dell Precision 5540) has no internal RJ45, so I'm stuck with the external ones... I also configured if_lagg on top of if_ure to use wifi when I unplug the Ethernet cable. The symptoms are losses of connections/packets. I don't see the DOWN/UP events from ue0 however. Perhaps they are "hidden" by the use of if_lagg. I enabled if_ure debugging with hw.usb.ure=1 but it doesn't log anything so far. I will try to capture USB packets using usbdump(8) as described in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244845 (another bug report about if_ure) and share everything I can. This is must be related to bug 252165. It is a race condition between ure_tick and ure_ifmedia_sts I'm trying to understand since some time... I'm currently using a workaround (bug 252165 comment 3) to get rid of the issue. I'm also experiencing this on FreeBSD leslie 13.1-STABLE FreeBSD 13.1-STABLE #0 stable/13-n251124-026e19496cc: Thu Jun 16 19:22:47 EDT 2022 root@leslie:/usr/obj/usr/src/amd64.amd64/sys/DEBUG amd64.

I recently got the mainboard replaced and haven't been having issues, but I'll need more time to test. |
