Unfortunately due to powerpc not being an officially supported
architecture, I don't think the updates I wanted to make to this kernel
qualify for a stable release update. I will however build a new set of
kernels and make them available for people to use, with this fix
included.

Also confirmed, 1.67GHz G4 Ti-Book, using jaunty's PPC kernel (v.
2.6.28-6-powerpc). Blue-background all.
Found bug #370200 as well... relevant or no??
Has Luke really been working on a kernel update for the past two months?
I hope it's ready now :-)

Thanks for this find. It should be easier to track down the cause of
this bug with git annotate on the powerpc kernel source tree for Ubuntu.
I also have an iBook G4 that appears to be showing the same behavior, so
testing the eventual fix should be easy for me at least.

I built K.org 2.6.29.2 and that works with DRM; this is probably
significant in that it uses the write combining drm_core_ioremap_wc(),
so it would appear that the Ubuntu patches for write combining are the
culprit:
In summary:
Ubuntu-pcc 2.6.28-6-powerpc [drm_core_ioremap_wc()] - fails
Further confirmation probably isn't necessary, but I've compiled and
tested 2.6.28.8 with success. Also, I've been having stability issues
with X since I've used the BusMode workaround, but I'm not sure yet if
they're related.

linux-image-2.6.28-5-powerpc has ioremap fault with radeon drm
Shortly after all this started, I built linux-
source_2.6.28.11.15_all.deb on PPC to see if that later version (the
source for then current ia32 version) had the fault, and it did on PPC.
Yesterday, following spydouglas' example, I built kernel.org 2.6.28.10,
which, as we now know, works on PPC.
Same here. Here's a image of the panic dump if that helps anyone (note
that the green dots are normal on my old machine in console mode).
