Even if the kernel is patched, the version 2.6.18 is not so recent :P
The system used version 1.0.3 of cryptsetup :/
Hmmm, why _twice_ and what for ?
Just temporary FS are encrypted. So the time spent depends of the size of the
FS. But sure, it's not user friendly :D

Ok, hard freeze is not good.
One thing you could try is a serial console. This needs only
a boot option to the kernel.
CentOS 5.5 is also pretty recent.

Unless Milan knows what is going on here, a recreation in
a test machine would probably be the best next step.
Hmm, do you by any chance encrypt swap _twice_?

BTW, pretty peculiar setup. I take it this machine installs
itself from an image to the encrypted filesystem (with random
key) on boot? JUst out of curiosity, how long does that
take?
