Comments/Problems:

On my network we have IPv6 enabled. I wanted to configure the new box IPv6 only with a fixed Address to test.

Booting off the RC1 ISO, I set following options

Regular install
Language: English
Country: Austria
Default Setting: en_US.UTF-8
Keymap: German

At the nameserver screen I go back twice to specify a fixed IPv6 Address.

IP Address: 2001:629:1005:323::161
Netmask: ffff:ffff:ffff:ffff::
Gateway: 2001:629:1005:323::1
Nameservers: 2001:629:1001:1::53 2001:629:1001:2::53

Then the screen stays blue and never goes on.

On console 4 I see the following logmessage looping:

nc_v6_interface_configured(eth0, scope global)
Running ip addr show eth0 to look for address
ip line: 2: eth0:<BROADCAST,MULTICAST,UP,LOWER_UP>  mtu 1500 qd isc pfifo_fast qlen 1000
ip line:     link/ether 00:50:56:be:XX:XX brd ff:ff:ff:ff:ff:ff
ip line:     inet6 2001:629:1005:323:250:56ff:febe:XXXX/64 scope global dynamic
ip line:       valid_lft 2591972sec preffered_lft 604772sec
ip line:     inet6 2001:629:1005:323::161/64 scope global tentative flags 08
ip line:       valid_lft forever preffered_lft forever
ip line:     inet6 fe80::250:56ff:febe:XXXX/64 scope link
ip line:       valid_lft forever preffered_lft forever



On console 2 I can ping both nameservers but the installer hangs at a blue screen.

Thanks
Philipp
