Hi Daniel,
Could you try the following patch?
You can apply this patch in freebsd 7.0 just by copying and
pasting to your shell.
Before you apply this patch, you can check as follows
if this works on your environment or not.
1. Set bootverbose mode.
cat >> /boot/loader.conf << EOF
boot_verbose="YES"
EOF
2. Reboot your machine.
3. Check the dmesg log of your HDDs as follows.
dmesg | grep ata
.
.
ata2-master: pio=PIO4 wdma=WDMA2 udma=UDMA100 cable=40 wire
^^^^^^^^^^^^
ad4: 115328MB <Super Talent Tech 02.10103> at ata2-master SATA150
ata3-master: pio=PIO4 wdma=WDMA2 udma=UDMA133 cable=40 wire
ad6: 953869MB <Hitachi HDS721010KLA330 GKAOA51D> at ata3-master SATA150
If you have a device like 'ad4' which is detected as
'udma=UDMA100', this patch will work.
