Any ideas?

please file a bugzilla on the fedora/redhat bugzilla and add rdsosreport.txt

Hello Harald,

Applied kernel parameters from link but I dont't get a shell. Very strange, it looks like if you wait for minutes it works well and I get a password prompt. But afterwards it is still slow on booting, but get the log file after some long waiting and tricks. It looks like it hangs in some endless loop when working on string operations.

Send you a private email with further private information about the issue (screenshots).

Will open a bug report later on.

Thanx for Harald figuring out/helping that with FC23 changed something: interfaces are not anymore eth0 but new interface naming schemes is now active e.g. ens18 Therefore dracut couldn't boot waiting for eth0 specified on kernel command line which didn't exist anymore because it is named now ens18.

As I use networking in initramfs with dracut and get networking up there you can't change the network interface easily (it is possible when you unload the network driver modile but for some reason this did not work reliable).

For reference: Nevertheless I found a solution to get persisent netnames in dracut and later on in the "regular" kernel.
# /etc/grub2.cfg kernel parameters
# before:
ip= nameserver= nameserver=
# after:
ifname=lan0:26:a0:fc:12:34:56 ip= nameserver= nameserver=
# and adapt network config and firewall to new interfaces

Harald, thnx for your help.
