That's a completely different issue to having a shutdown filesystem
hang your system. That's a mount problem, and likely a known issue.
You need to be specific when describing a problem, otherwise we
waste time going down the wrong paths.

Then hibernation has caused the corruption. It may take some time
for the corruption to be detected, but there isn't any doubt in my
mind that hibernation is the cause of your problems.

So, until we have kernel fixes, you'd do best to turn off
hibernation. If you can't live with leaving your machine powered up
or switching it off, then use suspend-to-ram rather than
suspend-to-disk to avoid the problematic snapshot/restore
situation....

Cheers,

Dave.
