Description NF 2004-02-16 09:10:14 UTC 
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.

Fix: 

in /boot/loader.conf.local, add:

  hw.ata.ata_dma=0 

to force drives into PIO4.
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.

Hand over to ATA maintainer. 

Does this problem still persist with a recent 5-stable, 6-stable or 
-current?
