Could you please post exactly what issue you're having? Are you saying
you mounted the filesystem on another system, then resumed hibernation
when the filesystem was already mounted? What kernel were you running
on the hibernated system? Please post all the exact errors you get
when attempting to mount the filesystem, including from dmesg
especially.

There actually is some protection on this, at least with more recent
kernels. Knowing exactly what you did, what kernels you're running,
and what errors you're getting now is crucial for narrowing any of
this down.
