Linux did the simplex device check. Your ALi controller only permits DMA
on one of the devices at a time. What is attached to the ALi controller
? Also does 2.4.19 base enable DMA correctly ?

If so then my guess is there is a bug in the changing of the pci setup
code in 2.4.20pre2-ac3, which shouldnt be hard to figure out
