Hi,
I have observed similar errors on amd64 7.1 RELEASE LiveDVD. http://forums.freebsd.org/showthread.php?t=1533 These looks T400 specific. I'm looking forward to using this machine with FreeBSD stable, so I hope these issues will be adressed in current soon.. All best, Jakub Lach

I believe that this problem may be fixed in ACPICA version 20080213: 13 February 2008. Summary of changes for version 20080213: commit 24a3157a90ddf851a0880c0b8963bc43481cd85b Author: Bob Moore <robert.moore at intel.com> Date: Thu Apr 10 19:06:43 2008 +0400 ACPICA: Fix for possible error when packages/buffers are passed to methods externally Fixed a problem where buffer and package objects passed as arguments to a control method via the external AcpiEvaluateObject interface could cause an AE_AML_INTERNAL exception depending on the order and type of operators executed by the target control method.

Thanks for information and kind assistance. If I understand correctly, Jung-uk Kim provides FreeBSD specific diffs of ACPICA. I will certainly try them.

Hello again.
Updated to ACPICA 20090123, got rid of ACPI errors, also got 2 ACPI warnings: ACPI Warning (tbfadt-0624): 32/64X length mismatch in Pm1aControlBlock: 16/32 [20090123] ACPI Warning (tbfadt-0496): Invalid length for Pm1aControlBlock: 32, using default 16 [20090123] |

You can ignore these, I think.

ACPI events

Hi all!
I have acpi events mapped to Fn+F7 (lcd brightness up) and to Fn+F8 (lcd brightness down), and several other combinations. I think the corresponding code in my `acpidump -dt` produced asl file is: <code> If (LEqual (Local1, 0x07)) { Store ("Fn+F7 Pressed", Debug) If (LEqual (OSYS, 0x07D6)) { If (IGDS) { BRTN (0x87) } Else { Notify (^^PCI0.PEGP.VGA.LCD, 0x87) } } Else { Store (0x15, SMIF) Store (Zero, TRP0) } Sleep (0x32) Store (0xB6, Index (DerefOf (Index (Local0, 0x02)), Zero)) Store (One, Index (DerefOf (Index (Local0, 0x02)), One)) } </code> and <code> If (LEqual (Local1, 0x08)) { Store ("Fn+F8 Pressed", Debug) If (LEqual (OSYS, 0x07D6)) { If (IGDS) { BRTN (0x86) } Else { Notify (^^PCI0.PEGP.VGA.LCD, 0x86) } } Else { Store (0x14, SMIF) Store (Zero, TRP0) } Sleep (0x32) Store (0xB7, Index (DerefOf (Index (Local0, 0x02)), Zero)) Store (One, Index (DerefOf (Index (Local0, 0x02)), One)) } </code> It is no effect when i pressed it, it is also no keycodes sent (tested with xev). The question is: how to debug usage of this combinations? Is there a way to get it work? Thanks! _______________________________________________ freebsd-acpi@... mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscribe@..." |
