Comment 8 for bug 659084

Got hit by #570542 at the same time.
The two issues seem to have some similarities between them in that they're both broken kernel modules in the -virtual that should've been available and seem to have been compiled in, or the build at least should've tried.

I've noticed that the -headers packages contain the same files overall, but the -image-virtual packages are missing both libahci.ko and the aforementioned .ko's.
