Here's what you do: 1) When first installing, before you partition the disks, jump to VT2 and run echo 1 > /sys/block/sda/device/queue_depth to disable NCQ during the install, or you'll get an error when the installer tries to access the disk. 2) Do your install as normal 3) Reboot to the CD again, choose Recover a broken system 4) Perform step 1 again, then pick the first option of the shells. 5) Run: echo "options sata_nv adma=0" >> /etc/modprobe.d/options 6) run update-initramfs -u This disables ADMA in the sata_nv module whenever it is loaded and also remakes the initrd with this change, so when you boot, it'll be correct.

echo “options sata_nv adma=0″ >> /etc/modprobe.d/options
6) run
update-initramfs -u
