>Description:
If there is an udma[66/100/133]-able device connected with a 40-pole cable to the nVidia nForce2 UDMA133 controller the udma mode is not reduced to udma33 in the boot process. This cause transfere errors and maybe data loss through wrong commands at the ata-device (even through they seems to be crc-protected). It also prevents reading the partition and slice tables and therefore creating the according devices in the /dev propperly.
The reason for that might be a bug in detection of the 40-pole cable which only supports modes up to udma33 or in reducing the mode to at most udma33 after detecting such a cable.

>How-To-Repeat:
Get a motherboard with such a chipset and connect an udma[66/100/133]-able device with a 40-pole ata cable to it.
>Fix:
add 'hw.ata.ata_dma="0"' to your /boot/loader.conf and enable the proper dma-modes after bootup with atacontrol mode <device> mode for each device.
