(Get the code!)
I believe the problem here is that all your BIOS' are configured to use AHCI. The current Ubuntu kernel is loading it as a module thus loading it very late. To add to this the kernel has another ATA driver compiled inside it which interacts with your disk controller and making it act in this bizare wait state.
After the AHCI module is loaded it fixes everything.
Proposed workaround: Disable AHCI in your kernel, enabling IDE or RAID as the alternative, this should stop the delay you seem to have. I tested it on my machine. Test it in yours so I can follow up.
Proposed fix: Compile AHCI into the kernel and not as a module.
