Gentoo is ridden with old versions of the various software you can emerge.
When you report problems you should always tell what version of the
software you are using.

Please post "dmraid --version" and "dmsetup version".  If your dmraid
is not -rc8, upgrade that.  If you're upgrading dmraid, there's a good
chance that you also need to upgrade the various dm stuff.

Sounds like one of the bugs that Heinz has fixed in the last couple of months.

Assuming that you've raided your disks in a RAID 1?
You just said that you created an 80 GB partition - what did you expect?

Odd.  Very un-informative of the kernel not to tell whether it found
problems or not.
