Any information will be helpful. It sounds very much like you have a cache coherency problem on your motherboard. This means that dma transactions to the 284X card in your machine don't invalidate any cache lines that reference memory that is modified by the dma, so you get inconsistent data. Try installing with your internal and external caches disabled in the BIOS and see if you can reproduce the problem. My other guess is that you are running into a bug in the aic7xxx driver. You may want to try installing 2.1-stable which has a much improved aic7xxx driver. > >Thanks. > > > -- Dan Malek -- Justin T.
