The problem is that with and without "text" option, it freezes
The best I get is (with beta) to go to a dracut shell with a boot line
such as, after removing "quiet"

... text ks=http://x.y.z.w/f18ks.cfg ip=... netmask=... gateway=..
dns=... vlanid=65

questions:
is vlanid usable?
I presume it is a video problem but it could also be something related
to SAN disks I don't want it to see, but
blacklist=qla2xxx
seems it doesn't work...
