My Dell Latitude laptopi on next-20160201 is throwing a similar error
at shutdown, except the traceback continues:

mei_me_remove+0xbd/0xc0
pci_device_shutdown+0x32/0x50
device_shutdown+0xe2/0x210

(sorry, that's all I have, transcribing from one frame of video shot while
the system was shutting down....)
