Additional info from Thomas Renninger:

> ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20070126]

I expect this to be ACPI (interpreter) unrelated and the bug should be in 
drivers/ata/libata-acpi.c. The problem is that libata-acpi.c calls _GTF 
function before _STM has been called. This is forbidden by ACPI spec. The 
Field is created in _STM. When _GTF is called first, an uninitialized Field is 
tried to be accessed. ACPI subsystem behaves correctly here.

Probably same as bug #8095
Comment 4 Len Brown 2007-03-08 15:43:29 UTC 
this goes away with libata.noacpi=1 ?

*** This bug has been marked as a duplicate of 7907 ***
Comment 6 Lukas Hejtmanek 2007-03-12 08:14:44 UTC 
with libata.noacpi=1 it is OK. 
Recodniging device as UDMA/33 has been another issue already solved.
