Description Jan Stodola 2014-12-08 14:15:49 UTC 
Description of problem:
Anaconda cycles in x3270 terminal early after starting the installation, trying to ask the user to select vnc or text mode. Unfortunately, no input from the user is accepted, so it is not possible to continue with the installation:

Anaconda should start sshd and prompt the user to login via ssh to continue with the installation.


Version-Release number of selected component (if applicable):
anaconda-21.48.16-1

How reproducible:
always

Steps to Reproduce:
1. start manual installation on s390x, do not specify any UI mode on the kernel cmdline

Actual results:
anaconda cycles in x3270 terminal, unable to continue with the installation

Expected results:
sshd starts, the installation continues via ssh

Additional info:
workaround is to specify vnc UI method on the kernel cmdline:
"inst.vnc"

Tested on compose http://s390.koji.fedoraproject.org/test/20141125/s390x/os/

Following patch (based on rhel7-brach) fixes this issue:
