--- Comment #6 from Eric Sandeen <sandeen@redhat.com>  2010-05-21 17:10:58 ---
Just to test a theory, could you try doing "hdparm -W" on your disk(s) to check
the write cache status?

If it's 1 (on), then prior to hibernate, can you try hdparm -W 0 on the disk(s)
and see if the problem persists?  I'm wondering if it's possible that data in
the drive's write cache got lost when the system powered down, if it wasn't
properly flushed during hibernate.

You'll want to do hdparm -W 1 later to turn them back on if that was the
original state.

Thanks,

-Eric
