I think I may have found a workaround.
Try adding the line: options libata noacpi=1
to /etc/modprobe.d/options, and then run the command: update-initramfs -u
then reboot.
That fixes the problem for me. I found this by accident while trying to get Ultrabay hotswap working.
AFAIK, the devs are planning to have an update to put this option in by default. Apparently, libata's newfound ACPI support has been a disaster.
