Hi,

I'm having problems with resume from suspend with this laptop. A lot of
the time it resumes perfectly, but sometimes it fails early.

During good resumes I see the following in my log:
ACPI Exception (exoparg2-0444): AE_AML_PACKAGE_LIMIT,
   Index (000000005) is beyond end of object [20080609]
ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.C2C3]
   (Node ffff88007e335e80), AE_AML_PACKAGE_LIMIT
ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.C003.C0F6.C3F3._STM]
   (Node ffff88007e33bdc0), AE_AML_PACKAGE_LIMIT
ata1: ACPI set timing mode failed (status=0x300d)

I have disassembled the ACPI tables using 'iasl' and found five obvious
syntax errors in the SSDT1 table (dump attached), of which one is in the
_GTM and two are in the _STM method. So that looks like an obvious cause.
I'm wondering if this could explain the resume problems.

If you cannot help me I'd appreciate some suggestions where to take this.


The first error looks like it may be a fairly simple fix:
@@ -64,8 +64,7 @@
                 CreateDWordField (Local0, 0x0C, C3F9)
                 CreateDWordField (Local0, 0x10, C3FA)
                 Store (C0FE (0x00, 0x00), C3F6)
-                Store (C101, 0x00)
-                C3FA
+                Store (C101 (0x00), C3FA)
                 If (And (C3FA, 0x01))
                 {
                     Store (C100 (0x00, 0x00), C3F7)

Or should that instead be
+                Store (C101 (0x00, 0x00), C3FA)
?


The next two I can't make anything of. They are very similar.
In the disassembly the first looks like:
<snip>
                If (LEqual (SizeOf (Arg1), 0x0200))
                {
                    Store (0x00, Local0)
                    Store (Buffer (Multiply (SizeOf (C2C2), 0x02)) {}, Local1)
                    While (LLess (Local0, SizeOf (C2C2)))
                    {
                        Store (DerefOf (Index (C2C2, Local0)), Local2)
                        Multiply (Local2, 0x02, Local2)
                        Multiply (Local0, 0x02, Local3)
                        Store (DerefOf (Index (Arg1, Local2)), Index (Local1, Local3))
                        Store (DerefOf (Index (Arg1, Add (Local2, 0x01))), Index (
                            Local1, Add (Local3, 0x01)))
                        Increment (Local0)
                    }

                    Store (C102 (0x00, 0x00, C3F6, C3FA, Local1), Local2)
                    Store (C106 (0x00, 0x00, C3F7, C3FA, Local1, Local3), \_SB.C2C3)
                    Local2
                    Local3
                    Local1
                    C3F4
                }
</snip>

The last 4 lines are obviously bogus. Does anyone here have a clue what
could be intended here?


The last two errors are in the _GTF method for two devices, again similar.
The first of those looks as follows:
<snip>
            Device (C3FB)
            {
                Name (_ADR, 0x00)
                Method (_GTF, 0, NotSerialized)
                {
                    Return (\_SB.C2CA)
                    C3F4
                    0x00
                }
            }
</snip>


Cheers and TIA,
FJP

P.S. There's also a warning from the DSDT table, but that looks relatively
harmless:
dsdt.dsl  9155:                         Wait (\_SB.C1AD, 0x10)
Warning  1103 -        Possible operator timeout is ignored ^

Can that be ignored or should I follow up on that too?
