The driver in 2.4.19-pre broke latest SiS chipsets in DMA modes. Some 650
were affected -> to be safe DMA was disabled for all of them.
Stock 2.4.19 should not fail but only disable DMA, could you confirm this ?

Won't be of much help here anyway :-)

The dump is rather usefull, especially if I know your BIOS config.
Here I assume that each controller is enabled and DMA activated for hda and
hdc, am I right ?
Happy AC compile :-)
