Hi,
I am using the Lenovo 2.5Gb/s USB-C to ethernet dongle but I keep experiencing an issue where the USB ports stop working. I noticed this after a kernel upgrade I think from 5.9.x or 6.0.x to what I'm running now which is the 6.1.x branch LTS.
The other non-Thunderbolt based USB ports also have started working strangely too in that I cannot get my camera which is a Nikon D500 to be seen as a mass storage device as there seems to be some weird power reset going on with the USB-A ports.
This is the kernel stack trace:

Should I post this trace upstream I wonder to Kernel development?
Thanks.
