I see the same. It comes from sys/dev/ic/ahcisata_core.c:ahci_intr_port
and apparently it is a fatal error:

        /* Handle errors */
        if (is & (AHCI_P_IX_TFES | AHCI_P_IX_HBFS | AHCI_P_IX_HBDS |
            AHCI_P_IX_IFS | AHCI_P_IX_OFS | AHCI_P_IX_UFS)) {
                /* Fatal errors */
                if (is & AHCI_P_IX_TFES) {
...

                        aprint_error("%s port %d: active %x is 0x%x tfd 0x%x\n",
                            AHCINAME(sc), chp->ch_channel, sact, is, tfd);


Can you show the dmesg part describing your ahcisata devices?

I get:

ahcisata1 port 2: active 2 is 0x40000001 tfd 0x2051

and the device is:

ahcisata1 at pci0 dev 17 function 0: vendor 1002 product 4391 (rev. 0x40)

ahcisata1: 64-bit DMA

atabus4 at ahcisata1 channel 2

and

On another machine:

ahcisata0 port 4: active 2 is 0x40000001 tfd 0x2051

and the device is:

Jaromir, could you have a look, please?
