The kernel messages that are shown in the links above do not show any "libata
version 3.00 loaded." message nor any ata/ahci message that I can see. So I
think the eSATA adapter is not even being detected and libata/ahci driver not used.

Was this working before ? If yes, can you try with the following patches reverted ?

d3243965f24a ("ata: make PATA_PLATFORM selectable only for suitable architectures")
3ebe59a54111 ("ata: clean up how architectures enable PATA_PLATFORM and
PATA_OF_PLATFORM")

If reverting these patches restores the eSATA port on this board, then you need
to fix the defconfig for that board.
