ICH5 ATA DMA timeouts

[Perry Hutchison]

Does anyone know the condition of the ICH5 ATA support in FreeBSD 10?

In preparing to repurpose an elderly Dell Dimension 4600 from Windows
to FreeBSD, and needing to decide what to do about drives, I found
several mentions in the archives* of ICH5 ATA DMA timeouts -- mostly
affecting the SATA ports, but the prevalence of SATA reports may
just indicate which ports were getting the most use:  a couple of
the reports involved the PATA ports.

While there have been commits to the ATA code since then, I didn't
find any definitive statement that the DMA timeouts had been fixed.
Did I miss something, or would I be better off using a separate SATA
or PATA PCI card instead of the ICH5's built-in ports?
