 It works for me:

 But I see joerg already changed things again, so this seems to be disk
 specific.

 Interesting! Even joergs recent change (ahcisata_core .c v1.53) did
 _not_ help in my situation / with my sata disk which still is not
 correctly detected (get the same error as before).

 Any hint what to change to narrow down the problem?

 Have you tried using a dedicated power source for the drive?

 Hmm, good point probably ... no, I haven't tried it (, yet).

 ATM ct and 2.5" sata disk are connected / supplied together from one
 single 5V/ 2.5A PSU. Maybe it's not sufficient (all the time).

 I wonder how to accomplish the separate power supply for the disk (I
 have no other 5V PSU available / at home).
 Would be a more powerful PSU (5V / 4A) replacement sufficient?

 Or would you recommend a complete separate PSU for the disk?

 Regards, Markus.

 FYI.
 My Cubieboard2 with any revisions of ahcisata_core.c does not recognize
 my ST9500325AS 2.5inch hard drive (powerd from cb2 board) at boot, but
 it does by "drvctl -r -a ata_hl atabus0" after boot.
 I tried to increase 2nd arg of ahci_exit_fis() around WDCTL_RST
 from 100 to 3000, then my cb2 recognizes my ST9500325AS at boot.
 When this harddrive is powerd from external power supply, not from cb2,
 it is recognized at boot without modifying ahcisata_core.c.

 I changed power supply for my cb2 from 5V 3000mA to 5V 4A but
 same result.

 It is a bit flacky with either version for me, so this seems to be a
 general problem with the AHCI chip.
