Workaround (tongue in cheek): if your system hangs and the disk activity
light stays on for 10 minutes or more - press the power button and hold
it down for 5 seconds!!!
My symptoms look more like a race condition caused by an implicit
assumption about how long it takes to format the swap partitio
Still not clear what the pattern is... howver, whenever I've had a
system that hung in boot because swap was "wrong", I've got out of it by
doing a boot in recovery mode. It appears that a recovery boot
serialises well enough that the system waits until swap/cryptswap is
formatted properly.
