Christopher, no issues with before upgrading to 15.10. A few days after the upgrade I noticed that the Laptop freezes from time to time and sometimes does not suspend, when I close the lid. That looks like an ACPI issue for me.
I am currently travelling abroad, so my options to reinstall or debug are limited. Do you have any idea, how I could get the ethernet interface working? I played a bit around and noticed that network interface is working from for a few seconds now and then. Looking at ping output, there are between 20 and 50 seconds "downtime" and meik@meik-Latitude-E7440:~$ ping 10.32.6.240 PING 10.32.6.240 (10.32.6.240) 56(84) bytes of data. 64 bytes from 10.32.6.240:
