    Last night I performed a simultaneous dd on the 4 drives on the Sil3124
    card like so:

    dd if=/dev/sda of=/dev/null
    dd if=/dev/sdb of=/dev/null
    dd if=/dev/sdc of=/dev/null
    dd if=/dev/sdd of=/dev/null

    Three times the system temporarily locked up and then lowered
    the speeds of the drives. They are currently at PIO4. What
    might be causing this?

    Here is the dmesg from when the problem occurred:
