Problem with VMAP_STACK=y

With kernel 4.8.0-01558-g21f54dd I get thousands of
"dvb-usb: bulk message failed: -11 (1/0)"
messages in the logs and the DVB adapter is not working.

It tourned out the new config option VMAP_STACK=y (which is the default)
is the culprit.
No problems for me with VMAP_STACK=n.

Thanks, JÃrg
