Bug#891036: Problem occurs in 4.13 and 4.14, but not in 4.12
I have repeated my tests, starting my Debian/testing system with the
4.13.0-2 kernel, and the same problem occured.
Then I have started the system with yet older 4.12.0-2 kernel
( uname -a returns: Linux wzab 4.12.0-2-amd64 #1 SMP Debian 4.12.13-1
(2017-09-19) x86_64 GNU/Linux )
Now the vhci_hcd driver loads correctly:
