Mikael,
Something worth trying: turn off CONFIG_IDE. That's what I need to
boot 2.6.39-rc[1-3] on PowerPC G5.
I know Jens has been fixing problems with IDE versus his plug/unplug
changes, but it's still not fixed for me in rc3.
In other mail http://lkml.org/lkml/2011/4/14/614
I see Linus recommending his post-rc3 commit 6631e635c65d
but I've not tried that myself yet.
Hugh
