As a bit of a tangent, if you see this fairly often, any idea why?
Journaling should in general protect you from needing any sort of fsck
after a power loss or oops; that's what they're for, right.  I'd be
curious to know what sorts of corruptions you wind up finding.

How the corruption gets coped with once found is one point worth
discussing, but where's it coming from in the first place?  My guess is
it's lack of barrier writes, but it's worth getting to the bottom of it,
and hopefully this will make the choice of e2fsck parameters less
relevant.  :)
