Setting qos=0 will generate a harmless warning, but the network still works. Using pio=1 should still be supported. I am bisecting the source. It will take a while as I still have 13 kernels to build and my PowerBook G4 takes about 6 hours per build - it is a lot slower than your computer. At this point, I know that kernel v6.1.0 works, and that v6.2.0-rc4 fails. If you can find a 6.1 kernel, it should work for you. Once I know the fix, we can explore having you patch and rebuild your 6.3.X kernel. Larry
