<div>Hello there,</div>
<div> </div>
<div>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). PCI mode works. After researching I found a old
bug that was fixed back in 2006 (<a
href="https://bugs.freedesktop.org/show_bug.cgi?id=6011"><font
color="blue"><u>https://bugs.freedesktop.org/show_bug.cgi?id=6011</u></font></a>)
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.<br>
</div>

<div>So the first question is, could this be the problem that
causes the lockups ?</div>

style="font-size:10pt;">Secondly, the patch that fixed the
bug (which is simple enough – it just aligns the aperture
to the aperture size due to an RV280 errata) cannot be
applied any more because the driver code
obviously has been completely re-organized. Could somebody
point me to where the code of the patch might be inserted
into the current driver code ? At the moment it's missing
from the code.<br>
