XFS/md/blkdev warning (was Re: Linux 2.6.26-rc2)

I've been getting this since -rc1. It's still present in -rc2, so I thought
I'd bug some people. Everything seems to be working fine.

I'm not sure who's to blame here so I've added a few people to CC; if I've
done so in error, sorry for the noise.

The taint is from loading a custom (fixed) DSDT which I've been doing for
ages, and which shouldn't affect this trace.
