Created attachment 256921 [details] traces from here: https://launchpadlibrarian.net/312961185/4.11.trace.txt RTL8153 connected via ASM1042A is used in Dell's TB15 and TB16 docks. So everyone using these docks is probably affected. What happens? - boot - connect to network - issue dmesg via ssh on a remote computer (not necessary but breakage simply occurs after some time, some people report that this occurs on high throughput) - get errors like "bad mac" on ssh or ssl - ethernet link is not usable anymore If I connect a RTL8153 to a different USB Port (not ASM1042A) everything works as expected. Ansis Atteka already digged into this issue. He wrote a mail about this here which may help any developer who looks into this: https://www.mail-archive.com/linux-usb@vger.kernel.org/msg85071.html There are bugreports on Ubuntu and Archlinux: https://bugs.archlinux.org/task/53998 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975 Attachments: Trace and dmesg retrieved from launchpad. Can still reproduce this with 4.11.3 I am able to test any provided patches :)

Please bring this issue up there, if it is still a problem in the latest kernel release.
