Subject: swsusp resume from dm-crypt over lvm?

Using the ability to echo the major:minor to /sys/power/resume from an
initramfs script I am able to resume from a lvm partition.

However, this doesn't seem to work if the swap partition is encrypted
and setup using cryptsetup (dm-crypt over an lvm partition that is).

Is this supposed to work or is it not feasible?

See Documentation/power/swsusp-dmcrypt.txt. Works for me.

Thanks, that helped...I had missed that the device must have the same
major/minor when resuming as it had when suspending.
