Hi Rick,
Unfortunately, all three of my Powermac G5 Quad's require the LCS to be
rebuilt.
Until i find the spare time to rebuild the LCS, i wont be building
kernels anytime soon.
I doubt that Debian PPC arch would make an official kernel package
specifically for the PMAC 11.2.
Either way, aside from the tweaked kernel config and perhaps a specific
cherry picked patch from ozlabs-ppc or nouveau project where required,
there isn't anything "special" about the kernels i have built which in
every other respect are just vanilla kernel.org source.
Not difficult at all to roll your own custom kernel. Just download
kernel.org source, install kernel-package and a appropriate version of
binutils as there was an issue with some recent versions not able to
correctly build a kernel (which may have already been resolved). Use my
kernel config as a starting point and tinker away building your own
kernel deb packages.
Cheers,
Peter

Hi Peter,
It looks like events have caught up with us. There’s now a 4.5.0 kernel in
Debian testing and strong hints that the kernel in Stretch, when it’s released,
will be based on 4.6. So your reconfigured 4.5.0-rc2 kernel is getting
out-of-date.
Which raises a couple of questions:
Is there any chance that your changes could make it into an official Debian package? Seems unlikely to me — because it’s very hardware specific — but we can always hope!
Do you have plans to make a 4.6 based kernel any time?
And finally, is there a hardware solution? Is there a non-Nvidia graphics card
I could purchase and install in my PowerMac-G5 that wouldn’t have the problem?
I don’t need anything fancy. Just enough to run a simple 2D mate or xfce
desktop.
From all of us who have benefitted from your work, a big “Thank you!”
Enjoy!
Rick

Hi Logan,
The kernel version is quite old (3.16.7). Perhaps you can try something newer.
Nouveau continually has improvements practically with each newer kernel version.
Perhaps something to consider, try the easy way out and use a pre-compiled
kernel deb package that i have available. I have kernels as new as 4.4.0
available suitable for Powermac G5's.
At least these could perhaps be a better baseline as these kernels are known to be
working for many Powermac G5's (AGP & PCIe GPU's along with a few generations
of nVidia GPU's (some even older than yours). Makes it easier to have a side by
side comparison.
Your call, link is below if interested.

Many have used them successfully in the past and have got their G5 Powermacs
running with nouveau.
I'm not so sure that MSI interrupts are ever enabled on AGP GPU's in the first
place (PCIe based GPU's are a different story).
It would be interesting to see your cat /proc/interrupts log as well.
Regarding your EDID issue, can you try the other DVI connector of your video
card or cable or alternatively try another display out if the issue still
persists.
Most Apple OEM ATI Radeon GPU's have their own issues as well. But that's
another story.
Regards,
Peter
