can you tell me more ? (What machine precisely, what .config etc...) ?
I tested here on two G5's:
- PowerMac7,3 aka Dual G5 AGP. This ones has U3 + K2 and uses cascaded MPICs
- PowerMac11,2 aka Quad G5. This one has U4 + K2 and uses a single MPIC in the northbridge
And both appear to work fine with today upstream (basically -rc1).
Cheers, Ben.
