Hi Jonathan,

I think it might need someone who really understands the Debian boot process to get their hands on a new iMac and sort this whole thing out. There are plenty of them around by now. I've got a lot of other things on my plate and this isn't a high priority for me.Might also be worth asking on debian-user@lists.debian.org if anyone has tried installing on a 2011 iMac.
I did earlier on -- I got no replies for over a week even though I followed up my own posts several times. I concluded nobody else had even tried at that stage. I might give it a month and then try again.
Sorry for the trouble and thanks for testing. As you saw with e.g. the "co" bug, we're not at a stage in the release cycle when the installer is completely polished yet. So at the moment, using the squeeze installer and then upgrading is more likely to be reliable.
That was the first thing I tried a while ago -- then somebody suggested I try the latest installer which is what I did.
If you do get a working installation, I would still be very interested in tracking down the radeon modesetting trouble (e.g., by taking a snapshot of the screen with artifacts and recovering any log entries that appear before then). I suspect the cause is similar to Bug#637943 (modesetting not working correctly without firmware-linux-nonfree installed).
Hmmm - interesting. I might check Ubuntu forums too. But I'm not in a particular hurry -- I've just installed MacOSX 10.7 (Lion) and I've got heaps of other things to keep busy with :-)
Cheers, Mike.
