[regression] 2.6.39-rc[1-3] fail to boot on G5 PowerMac

FWIW, the problem Ben refers to might be fixed in current mainline by
commit d87dfdbfc91c5e37288e7e8f7afdd992ba61a60d which reverts

[regression] 2.6.39-rc[1-3] fail to boot on G5 PowerMac

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://www.yqcomputer.com/
I see Linus recommending his post-rc3 commit 6631e635c65d
but I've not tried that myself yet.

Thanks for that, Ben: I remember you were brewing up such a driver,
but I missed when it actually went in. I can confirm that switching
off CONFIG_IDE and switching on CONFIG_PATA_MACIO and
CONFIG_BLK_DEV_SR now gives me a booting system with a working CD-ROM
(though I've not yet tried burning).

Whereas CONFIG_IDE=y with current git still does not boot: hangs for a
minute or three around the windfarm announcements, then an endless
splurge of hda error messages - sorry, I'm not being helpful, other
worries...

Yes, that also boots, with a working CD-ROM: thanks.
