>Description:
Tried FreeBSD 5.2.1-RC2 on a Dell PE600SC machine.  Said machine has "ServerWorks CSB6 UDMA100"  controller.  If HDs are running at UDMA100, data get corrupted.
>How-To-Repeat:
Install FreeBSD 5.2.1-RC2 on a Dell PE600SC machine.  After installation, IDE drives should be running at UDMA100.  Do this:

   tar zcvf /path/to/sometar.gz /usr

then:

   gunzip /path/to/sometar.gz

will results in unrecoverable CRC errors.  Or, try compiling the kernel.  It'll fail with numerous "file not found" errors.
>Fix:
in /boot/loader.conf.local, add:

  hw.ata.ata_dma=0 

to force drives into PIO4.
