Thank you for looking at the issue Lakshmi.
Indeed, I forgot to put the debug flags...
This time the bug cause only one of the kernel oops I had in the previous
cases, and this is in a kworker context instead of in the Xorg one (time 37.197
in attached dmesg).

It occurs 100% of the time, as far as I tested, when I hotplug the adapter.

Maybe I missed something, I believed my attachments contained the whole boot
info. Which additional information is missing and do you have some pointers on
how to get it?
