Ah ok, I haven't seen these problems. Ben, any idea ? I was trying to make nouveau the default instead of nvidiafb on G5's but it seems like some old G5's with those NV34 aren't happy. BTW. Are we trying to use AGP on these things ? If yes, I would suggest we just blacklist AGP on all powermac unless specifically requested via a kernel command line arg. That would be half of the problems solved... I have access to an iMac G5 with an old 5200 variant as well which I could dig out & try if there's anything I can do to help debug that. (On my G5s it's all PCIe so that problem doesn't happen). Cheers, Ben.
