>Description:
A clean installation using FreeBSD media cause errors when DMA mode is used to access the IDE disks.

messages during installation:
ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2570528
ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2570624
ad0: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=2574752

if system is installed using hw.ata.ata_dma=0 the following happens, when system is booted with DMA enabled:

system is working fine with hw.ata.ata_dma=0:

>How-To-Repeat:
Try to access IDE drives in a Sun Netra X1 using DMA mode. Tested FreeBSD installation media 5.3-RELEASE and 6.0-CURRENT-SNAP004. Earlier releases no testet.
>Fix:
If DMA is not used (hw.ata.ata_dma=0 in bootloader) the messages go away and access to HDD is possible without errors, but only in PIO4.
