dmesg (Radeon on PCIe x8, no IOMMU bypass)
So, today I tried moving the Radeon card from the x16 to the x8 slot, and it
initialised correctly, as you can see in the attached dmesg. This bug is most
certainly caused by some kind of interaction between the card and the IOMMU
(bypass). Can someone please take a look at this? Like I wrote before, I'm
willing to provide ssh access to the machine (Power Mac G5), if the bug is hard
to reproduce. Thanks in advance!</pre>
