Compaq Armada E500: tried to fix dsdt; need a little help

[Sebastian Kemper]

Hello again,

with the help of a HowTo at Gentoo's forum I was able to fix most of the 
errors. But some remain and I would like you to take a look. I would 
really appreciate it if you read the full story in the Gentoo forum, 
because the formatting is better so you get a better insight in this 
matter and I already fixed many bugs but I'm not sure if my fixes are 
good. So If you would go to 
http://forums.gentoo.org/viewtopic.php?t=122145&postdays=0&postorder=asc&start=27 
I really appreciate it. Thanks!

This is what iasl now says:

The interesting parts in dsdt.dsl look like this:

2159 Method (_PCL, 0, NotSerialized)
2160             {
2161                 If (\_SB.C005.C013.C059.C08A ())
2162                 {
2163                     Store (Package (0x00) {}, Local0)
2164                 }
2165                 Else
2166                 {
2167                     Store (Package (0x01)
2168                         {
2169                             \_SB
2170                         }, Local0)
2171                 }
2172
2173                 Return (Local0)
2174             }

And I don't have a clue what to do here. I tried to change 'Package 
(0x00)' to 'Package (0x02)' and the warnings dissappeared. But I didn't 
know what I was really doing so I reversed my changes.

Another one is this:

dsdt.dsl   735:                 Return (^C08E (Arg0, Arg1, Arg2))
Error    1029 -                             ^ Called method returns no value


I read something about about "Return(Package(0x02){0x00, 0x00})" and 
thought "Hey, I gotta have one of these"

Code:

Method (C08E, 3, NotSerialized)
             {
                 Acquire (^C082, 0xFFFF)
                 Acquire (\_GL, 0xFFFF)
                 ^C08B ()
                 Store (0x07, C05B)
                 Store (Arg0, C05C)
                 Store (Arg1, C05B)
                 Store (Arg2, C05C)
                 ^C08C ()
                 Release (\_GL)
                 Release (^C082)
             }

             Method (C08F, 2, NotSerialized)
             {
                     Return (^C08D (Arg0, Arg1))
             }

             Method (C090, 3, NotSerialized)
             {
                 Return (^C08E (Arg0, Arg1, Arg2))
             }


changed to

Code:

Method (C08E, 3, NotSerialized)
             {
                 Acquire (^C082, 0xFFFF)
                 Acquire (\_GL, 0xFFFF)
                 ^C08B ()
                 Store (0x07, C05B)
                 Store (Arg0, C05C)
                 Store (Arg1, C05B)
                 Store (Arg2, C05C)
                 ^C08C ()
                 Release (\_GL)
                 Release (^C082)
              Return(Package(0x02){0x00, 0x00})
             }

             Method (C08F, 2, NotSerialized)
             {
                     Return (^C08D (Arg0, Arg1))
             }

             Method (C090, 3, NotSerialized)
             {
                 Return (^C08E (Arg0, Arg1, Arg2))
             }

But the writer of the dsdt HowTo at Gentoos forum said this may be not a 
good fix. What do you think?

Thanks

Sebastian

Could you describe what kind of ASL error that need to be fixed?
In some cases, some ACPI interpreter bug could be found!
