USB ethernet hangs

I'm using an USB ethernet device, which causes hangs recently. When rebooting the device, I get lots of

r8152 4-2:1.0 enp51s0f4u2: Tx timeout

... without it successfully killing anything (I had to hard reboot).

There's also a hang in the kernel messages:

INFO: task NetworkManager:1080 blocked for more than 122 seconds.
      Tainted: P        W  OE      6.5.9-zen2-1-zen #1
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
task:NetworkManager  state:D stack:0     pid:1080  ppid:1      flags:0x00000002
