Description Andrew Hatfield 2017-02-01 09:59:56 UTC
Description of problem:

If you have a root partition protected with LUKS and restart with 'reboot', on next boot you are never prompted to enter your LUKS passphrase and the boot never completes.

Version-Release number of selected component (if applicable):
Fedora 25
4.9.6-200.fc25.x86_64 and 4.9.4-201.fc25.x86_64

How reproducible:
each time

Steps to Reproduce:
1.  log into gnome as a normal user
2.  Open gnome-terminal
3.  sudo su -
4.  reboot

Actual results:
At boot screen the LUKS passphrase prompt is not displayed as it is from a cold poweron.  Boot never completes, waits indefinitely

Expected results:
Same behaviour as cold poweron and grub / plymouth displays LUKS passphrase.

I think that's unlikely. There is very little difference between a reboot and a cold boot. Maybe try booting without "quiet rhgb" on the kernel commadn line and enter the password through the text interface.

I've just tested this again on Fedora 25 4.10.10-200-fc25.x86_64 and it correctly prompts for LUKS passphrase at boot time
