sorry about that.
Anyway, i checked drivers/gpu/drm/radeon and
drivers/char/agp/uninorth-agp.c and can't seem to find the patch
indicated below. Might it have gone missing :-) ?

I’m running a RV280 based Radeon 9200 card (I know, an ancient card)
in a Mac Mini G4 (powerpc-architecture) with Ubuntu Precise and the
latest 3.4.64-kernel/ati driver and get lockups when trying to run the
card in AGP mode (KMS enabled). The lockups happen when resetting the
card (that’s what I can infer from the oops-screen).
It's the other way around: The kernel radeon driver resets the card to
try and get it running again after a lockup.
PCI mode works. After researching I found a old bug that was fixed
back in 2006 (https://bugs.freedesktop.org/show_bug.cgi?id=6011) that
looks like the freeze I experience (since PCI mode – which allocates
64 MB of memory - works and AGP mode which by default allocates 256 MB
doesn’t). The card has 64 mb memory.
So the first question is, could this be the problem that causes the
lockups ?
Not really. The GART and VRAM memory apertures aren't directly related,
and the fix for the bug above should still be incorporated in the
current radeon KMS code.
Does radeon.agpmode=1 or radeon.agpmode=4 work?
Thank you for your reply. First, none of the agpmodes work, they just
take more or less time to lockup the card (1 - slowest, 4 fastest).
Secondly, if you write that the fix "should be incorporated in the
current code", i'm somewhat lost because it definitely isn't there.
It's in the kernel now.
Well........no. I checked the 3.4.64 kernel sources after my last Mail
and the code isn't in the drivers/gpu/drm/radeon sources. But of course
i might have overlooked something.
