Following up on this bug I have found the location of the OOPS in source
code (using bisection). It's clearly not the source of the problem, but
I hope it will help.
In the file drivers/usb/class/cdc-acm.c, around line 1098, there is a
comment "/*workaround for switched interfaces */" and then a check:
if (data_interface->cur_altsetting->desc.bInterfaceClass !=
CDC_DATA_INTERFACE_TYPE)
At this point, the variable data_interface is NULL and this causes the OOPS.
