Hi Elmar,
I don’t know if it may be of help, anyway I have a similar problem: the point
is that my problem does not seem related to graphic drivers. My OS is
Slackware64 14.2, kernel 4.17.0. At boot, after the usual kernel messages, this
is what I see, at the end, on the screen (please, note that I boot in non
graphical mode, that is in init 3):

Welcome to Linux 4.17.0 (tty1)

darkstar login: [   15.869206] wlan0: authenticate with 64:59:f8:cd:3a:88
[   15.887504] wlan0: send auth to 64:59:f8:cd:3a:88 (try 1/3)
[   15.892825] wlan0: authenticated
[   15.895108] wlan0: associate with 64:59:f8:cd:3a:88 (try 1/3)
[   15.899592] wlan0: RX AssocResp from 64:59:f8:cd:3a:88 (capab=0x411 status=0
aid=3)
[   15.900872] wlan0: associated

as you can see, after the welcome message I can’t insert my login username – 
because of the extra messages related to wlan authentication/association –  and
as a consequence the system gets stuck.  However, (in my case) we are dealing
here with a “trivial” bug, since it suffices to press Enter in order to restore
the login prompt and then start X.
I don’t know if this bug may be related to yours: in any case I would try to
boot in runlevel 3 in order to see what happens.
All the best, 
Giorgio
