Stack trace in dmesg when loading driver and replugging device #976

Open delbonis opened 2 years ago

delbonis commented 2 years ago

Using tag v5.6.4.2, whenever I load the driver with the device plugged in, or replug the device with the driver loaded, I get this error in the output of dmesg -wH:

I'm on kernel 5.13.0-48-generic #54-Ubuntu. This wasn't happening before a few days ago, it also happens on the -50- version of the same Ubuntu kernel release line.
