Description Olivier Mondoloni 2007-02-27 02:51:35 UTC

Most recent kernel where this bug did *NOT* occur: 2.6.20.1
Distribution: Gentoo Linux
Hardware Environment: Asrock 775DualVSTA Bios P2.20 Intel E6400 Core2Duo CPU
Software Environment: Gentoo Linux console environment
Problem Description: A lot of acpi error in kernel log related to pata_via
(method parse/execution failed).

Steps to reproduce: try 2.6.21-rc1-git2 kernel on the above hardware configuration.

scsi2 : pata_via
ACPI Error (dsopcode-0481): Attempt to CreateField of length zero [20070126]
ACPI Error (psparse-0537): Method parse/execution failed 
[\_SB_.PCI0.IDEC.RATA] (Node ffff810001fc44f0), AE_AML_OPERAND_VALUE
ACPI Error (psparse-0537): Method parse/execution failed 
[\_SB_.PCI0.IDEC.CHN0.DRV0._GTF] (Node ffff810001fc4850), AE_AML_OPERAND_VALUE


This is probably caused by one of the drivers incorrectly calling _GTF before 
_STM has been called.

Comment 10 Olivier Mondoloni 2007-03-02 15:30:23 UTC

Thanks for this explication.

Comment 11 Robert Moore 2007-03-02 15:34:01 UTC

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.

Nothing changes. ACPI errors are still here.

Comment 14 Len Brown 2007-03-08 15:42:59 UTC

this goes away with libata.noacpi=1 ?

Comment 16 Olivier Mondoloni 2007-03-09 01:48:26 UTC

Acpi errors goes away with libata.noacpi=1 kernel parameter.

Always acpi errors related to pata_via.

No problem with the boot kernel parameter libata.noacpi=1.
ACPI errors goes away.
