This indicates the SATA controller reported an error for a command that had already completed, or for a command slot that wasn't in use at all. Can you narrow it down to one of the SSDs in that system? Do those SSDs work properly in other machines? Are you able to build a custom kernel and boot it on the APU? If so, the first thing to do would be to enable ahci debug output by changing the #define NO_AHCI_DEBUG line at the top of src/sys/dev/ic/ahcivar.h - this won't fix the panic but it'll tell us where the error information is coming from. Depending on what output you get from that, there are a few more things to try.
