Since updating my Lubuntu 16.10 system (linux-image-4.8.0-37-generic to linux-image-4.8.0-38-generic) the kernel panics as soon as I plug in the Wifi Adapter (Edimax EW-7612UAn Wifi USB Adapter).

This is followed by the Modules linked in, Hardware info, Stack trace.
At the end of the trace it says:
Kernel panic - not syncing: Fatal exception in interrupt.

I uploaded a console screenshot to my google drive: https://goo.gl/medcXj
and I didn't find anything suspicious in syslog or kernel log, most probably because the kernel panics almost instantly after plugging the usb adapter in.

Updating to linux-image-4.8.0-39-generic does not solve the issue as well.

Only way to work around the issue is to select the 4.8.0-37 image from the grub bootmenu.
The problem is not related to a specific USB port.
