    HD DMA off, CD DMA on, works.
    HD DMA on, CD DMA off, locks system.

    I didnt want to do a reinstall, so I just copied files from CD to test. "cp
    -R /cdrom/ /home/"
    Both are UDMA(66) in the startup mesg.

    At least we know its DMA on the HD.

    Thanks!

     unmaskirq = 0 (off)
     using_dma = 1 (off)
     keepsettings = 0 (off)
     nowerr = 0 (off)
     readonly = 0 (off)
     readahead = 8 (on)
     HDIO_GETGEO_BIG failed: Invalid argument

    root@stonecold:~ # hdparm -v /dev/hdb
