        Processor: 400Mhz celeron
        Memory: 128M
        Disks Used: Western Digital 45G eide standalone or Maxtor 15G eide
                standalone. (Both failed in pciide mode)

>Description:
Desc:   Enabled pciide causes system to completely freeze (no ddb esc)
        when dealing with high volume i/o under the system set described
        below. The high volume i/o came from a transfer of 200 - 700 Megs
        of mp3s at around 800/900 k/s. System would freeze in the 200 -
        700M range.
>How-To-Repeat:
Enable pciide in the kernel under a system with no bus support for udma when using disks that claim udma support ???

>Fix:
Disable pciide in the kernel.
