I get this on the 440LX with the same DMA timeout message. Everyone says it's
the board's fault as well. Funny. Anyways this happens accross just about
any Dev kernel but more so in the -test12 and up versions. . Test10 works
fine without locking. Blaming the hardware reminds me of the help given by
some other company I can't seem to remember the name to.
