Not sure if I should have canceled those upgrades after:Yes, your packages are no up-to-date if you're still on glibc_2.25.
They weren't up-to-date before doing `apt -f install` as I downgraded to the version of libc I had before doing the upgrade yesterday. But libc got updated to 2.26 during `apt -f install` - a recent segfault message also shows this:
```v245 login: [ 46.563987] e1000e: enp8s0f0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: Rx/Tx

```Only the other (systemd related) packages I downgraded earlier were still on the older versions after the reboot. But I now did an `apt dist-upgrade` with `/etc/apt/sources.list`:
``` deb http://ftp.ports.debian.org/debian-ports/ sid main deb http://ftp.ports.debian.org/debian-ports/ experimental main deb http://ftp.ports.debian.org/debian-ports/ unreleased main ```..so they should be up-to-date now. But that also didn't help, after a reboot, segfaults still happen when trying to login via serial port.
