I see a syslog saying that this DSDT.aml is detected and loaded.
However, I get errors as follows:
ACPI-0508: *** Error: Method execution failed [\_SB_.BAT1._BST] (Node
cbed7be0), AE_NOT_FOUND
ACPI-0362: *** Error: Looking up [Z007] in namespace, AE_NOT_FOUND
... ad infinitum.
Those Z00X objects should get fixed as soon as the next big ACPI patch from
Len goes mainline.
This should be interesting for a lot people here, currently patching
there DSDTs because of this error.
See: http://bugzilla.kernel.org/show_bug.cgi?id=5322
I expect you used an iasl compiler newer than 20051216 that already includes
the fix and therefore does not complain about the missing Z007 object.
Your kernel is probably still missing this fix and constantly complains.
You may want to patch 2.6.16-rc1 with Len's latest patches:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test/2.6.16/
If you try this out, I'd be glad if you could report back whether the
Z00X issue is really finally solved for you.
Puzzled - especially since Z007 does not appear in dsdt.dsl (replaced by
"ones" on advice from this forum - a la acer laptops and Z007 being
nonexistant anywhere.)
...
which provides the following error:
Error 1061 - Object does not exist (\_PR.CPU0._PPC)
The object is probably declared in SSDT.
acpidmp >/tmp/acpidmp
acpixtract ssdt acpidmp >ssdt
iasl -d ssdt
To get rid of the compiler error just declare it:
External (\_PR.CPU0._PPC)
So that the compiler knows it is declared in some
other, later loaded ACPI table.
This appears six times overall, across methods:
_Q8A, _Q8D, _Q8D ... which seem unhelpful.
I see /proc/acpi/processor/CPU0 contains files;
info limit power throttling
I see that _PPC is a reserved method name:
_PPC Method with 0 arguments, must return a value
It is probably because of the above missing external().
If the Z00x is your only problem, don't waste time by trying
to rewrite your DSDT, better try out Len's patches
and let us know if you still see anything bad.
