Hello,

After upgrading one machine it does't boot anymore. Booting the old FC22 kernel works well.

Reached target Basic System.
Found device /dev/mapper/luks-9fbecd95-508a-45ca-997a-42a613c4e5bf Found device /dev/mapper/fedora_hostname-root

Also integration of ssh preboot authentication is not available anymore.

Please follow up here with the bugzilla ID, as I had a similar problem.

My solution was to create a "BIOS Boot" partition where one previously didn't exist then reinstall grub. I really don't know if all that I did was necessary, or if there was something else in my process that actually fixed it, but I've had to do it on a few machines now and it's fixed it every time.

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.

Ciao,
Gerhard

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=1.2.3.4::1.2.3.1:255.255.255.0:myhostname:eth0:off nameserver=8.8.8.8 nameserver=8.8.4.4
# after:
ifname=lan0:26:a0:fc:12:34:56 ip=1.2.3.4::1.2.3.1:255.255.255.0:myhostname:lan0:off nameserver=8.8.8.8 nameserver=8.8.4.4
# and adapt network config and firewall to new interfaces

Harald, thnx for your help.

Gerhard
