Very strange indeed. Is this repeatable?
LUKS itself does not need any time to activate. LVM
should not need more than fractions of a second.
Meybe a thermal issue with RAM, CPU or PSU that has the
password iterations fail when cold and work when warmed
up? For CPU/RAM this would be strance as cold CMOS
circuits work better than hot ones. For the PSU, it
is possible that failing capacitors reconstiture a bit
after warm up. Anyways, sounds like a hardware issue to
me.
