Description of problem:
When I switch on my computer (F20 system, installed on a SSD with LVM + encryption), there is a 50% chance that it wont boot. Instead of asking me the password to decrypt the drive, the system will stay stuck for a few minutes and then fall back to the emergency shell.

I get the following warnings:

dracut-initqueue[228]: Warning: Could not boot.
dracut-initqueue[228]: Warning: /dev/fedora_tokyo/root does not exist
dracut-initqueue[228]: Warning: /dev/fedora_tokyo/root does not exist
dracut-initqueue[228]: Warning: /dev/fedora_tokyo/swap does not exist
dracut-initqueue[228]: Warning: /dev/fedora_tokyo/swap does not exist
dracut-initqueue[228]: Warning: /dev/mapper/fedora_tokyo-root does not exist
dracut-initqueue[228]: Warning: /dev/mapper/fedora_tokyo-root does not exist
dracut-initqueue[228]: Warning: /dev/mapper/fedora_tokyo-root does not exist
dracut-initqueue[228]: Warning: /dev/mapper/fedora_tokyo-swap does not exist

The system also generates a file "/run/initframfs/rdsosreport.txt" with potentially interesting info but I haven't been able to mount a USB key to save it (I'm a bit of a CLI noob).

Version-Release number of selected component (if applicable):
Dracut: 034-64.git20131205.fc20.1
Linux: 3.13.7-200.fc20.x86_64
The problem has existed since I installed F20, a month or so after its release.

How reproducible:
More or less 50% of the times I boot up, but without any predictability.

Steps to Reproduce:
1. Boot a computer with F20 on an encrypted drive
2. Watch the Plymouth "bubble" fill without asking for a password to decrypt the drive
3. Wait a few minutes before being switched to the emergency mode (shell with "dracut:/#")

Actual results:
System does not boot sometimes. Must be powered off and then rebooted, sometimes several times in a row, before 

Expected results:
System should boot every time.

What is your kernel command line?

# cat /proc/cmdline

Comment 2 Jordan 2014-04-01 11:55:18 UTC
cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-3.13.7-200.fc20.x86_64 root=/dev/mapper/fedora_tokyo-root ro rd.lvm.lv=fedora_tokyo/swap vconsole.font=latarcyrheb-sun16 rd.luks.uuid=luks-05c66645-73e1-4eea-b15f-020126f1bab0 rd.lvm.lv=fedora_tokyo/root rhgb quiet LANG=en_US.UTF-8

Comment 3 Harald Hoyer 2014-04-01 13:12:16 UTC
try instead of:
rd.luks.uuid=luks-05c66645-73e1-4eea-b15f-020126f1bab0 rd.lvm.lv=fedora_tokyo/root


rd.luks.uuid=05c66645-73e1-4eea-b15f-020126f1bab0 rd.lvm.vg=fedora_tokyo

Also what is the output of:

# cat /etc/crypttab
# lsinitrd -f /etc/crypttab

Comment 4 Jordan 2014-04-01 21:36:00 UTC
[root@tokyo jordan]# cat /etc/crypttab
luks-05c66645-73e1-4eea-b15f-020126f1bab0 UUID=05c66645-73e1-4eea-b15f-020126f1bab0 none

[root@tokyo jordan]# lsinitrd -f /etc/crypttab

I'm not sure what you mean by "try instead [...] fedora_tokyo"? I'm a bit of a newbie.
