I have been using the following modification for a couple of weeks now to both
the 2.4.19 and 2.4.20-pre11 kernels on an MSI KT3 Ultra2 board (has the 8235
southbridge) and have not had any problems with the hard drives or DVD/CDRW
drives in the system running in UDMA mode.
The code modification comes from a patch that was posted to the list a while
back by Vojtech.
