Agreed. Let's look at the error messages...

The dock driver called _DCK, which was successful. So, the dock driver did its job.

This message came from ata_eh_link_report(), which indicates that there was an ATA link error detected.

This indicates that the target device, which I think the battery bay, was gone.

So, it looks to me that the battery bay was undocked, but an ATA link error was detected. This could be either a new FW causing the ATA link error or the ATA stack detecting the link error which didn't before.
