Um, this was marked as resolved, until you reopened it and then reset
the state to New.  Why did you do this?

It's fixed in mainline as of commit d4da6c9 when Linus reverted commit
d0646f7.  Users could still see it if they mount a file system with -o
journal_checksum, but (a) it's no longer the default, and (b)
corruption if you use the non-default journal_checksum mount option is
not a regression.

We have fixes to make journal_checksum safe queued for 2.6.33, but the
revert fixes the regression problem.
