=sys-kernel/dracut-031-r1 works fine.
I use these kernel options:
kernel /vmlinuz rd.lvm.lv=ssd/usr root=UUID=6efd858c-8237-40b8-9931-1aa1f27bba0b rootflags=rw,relatime,user_xattr,barrier=1,data=ordered rootfstype=ext4

Why it waits for activation of /dev/mapper/crypt-swap? Do you have a "kernel_cmdline" option in dracut.conf or dracut.conf.d?

I don't have kernel_cmdline option in dracut.conf nor in dracut.conf.d. 

I have crypt-swap configuration in conf.d/dmcrypt:
swap=crypt-swap
source='/dev/raid0/swap'

and fstab:
/dev/mapper/crypt-swap    none                            swap            sw                              0 0

"swap" is logical volume of "raid0" volume group which is located on raid0 mdraid array.

Please generate initramfs with dracut-033-r1 and post the output of following commands:

# lsinitrd /path/to/initramfs | grep 'hooks/emergency'
# dracut --print-cmdline

[Comment 5 Alexander Tsoy 2013-10-06 20:52:26 UTC]

I think you can ignore my previous comment. Looks like possible workarounds/solutions would be:

1. Create a fake /etc/crypttab:
# echo 'crypt-swap /dev/raid0/swap /dev/urandom swap' > /etc/crypttab
Then dracut will not include this device into host_devs stack. (Also see bug 429966 - I hope the migration will ever happen. :) )

2. Wait for upstream fix of "- remove wait for swap devs, if no "resume=" is given on the kernel command line"
http://git.kernel.org/cgit/boot/dracut/dracut.git/tree/TODO

3. Activate encryted swap in initramfs.

[Comment 6 Alexander Tsoy 2013-10-06 21:25:09 UTC]

And message "Partial mode. Incomplete logical volumes will be processed." is not related to this issue. It's just a warning shown by lvm when --partial option is passed.

[Comment 7 Alexander Tsoy 2014-03-15 22:03:24 UTC]

Any news on this bug? Does adding swap to /etc/crypttab help?
