Output of SysRq-T

I'm using a Dell laptop (Inspiron 7373) with a USB ethernet adapter (17ef:7205
Lenovo Thinkpad LAN, driver r8152). Sometimes, after resume, network-related
utilities (e.g. ip, ping) freeze in D state. No communication over IP networks
is possible. Attached is SysRq-T from the malfunctioning state.

From my POV, the following stand out:
