ThinkPad USB-C Dock Gen2: various kernel warnings

2021-06-08, 20:08 PM

I have a ThinkPad USB-C Dock Gen2 to connect my T14 AMD to. In the logs, I find the following warnings:

 

kernel: r8152 3-1.1:1.0 (unnamed net_device) (uninitialized): Invalid header when reading pass-thru MAC addr

kernel: usb 3-1.3.4.4: Warning! Unlikely big volume range (=3072), cval->res is probably wrong.
kernel: usb 3-1.3.4.4: [5] FU [Mic Capture Volume] ch = 1, val = 4608/7680/1

 

I guess these are issues that Lenovo should report to their upstream (Realtek for the first issue) or fix themselves (ThinkPad USB-C Dock Gen2 USB Audio for the second issue).
