Comment 1 for bug 1174325

I have exactly the same problem.

One thing to note is that if you read the dmesg log without grepping, there is a line right after every "emu1010: Audio Dock Firmware loaded" line stating the Audio Dock version is "0.0", meaning that the module is failing to read both major and minor version numbers.

Also, I found a work around that at least works for me.
1. Reboot to kernel 3.5.x using GRUB
    The firmware should load without problem
    (although nothing else works because everything is built against 3.8 kernel)
2. Don't turn off the micro dock and reboot back to kernel 3.8

It seems that as long as I don't turn off the dock, it keeps working even after system reboot/shutdowns.
