But you *did* read the release notes (including bug reports) *prior* to
trying 10.04... right? To be quite honest I'm clueless when it comes to
RAID. But I think that prior to trying 10.04 on a RAID, and having read
the release notes first, I'd be hesitant to try 10.04 until the issues
are/were resolved.

Suggest that you file a bug report on launchpad (no, not being facetious
here, I'm seriously suggesting you do this). Doing so may likely help
10.04 final, and help sort out your issue.
