Re: RV: [ACPI] differences between acpidump and disassembling

[Emilio M. F. de V. <em...@ie...>]

Hello Sergio,=20
Here I send you the files as you asked:
By the way, I have posted a new thread because there is one small differenc=
e=20
respect to the first message that I sent, concerning to the missing=20
parameters in DefinitionBlock when I used acpidump to retrieve the dsdt=20
table.
This was due to an error while compiling the program acpidump. Now I have=20
fixed it and the only difference between the results with acpidump and the=
=20
method that you propose -getting the table from /proc/acpi/dsdt and=20
decompiling- is the missing return package in WAK function.

I guess you mean grep -i acpi, with lower-case. don't you?
Anyway, I attached the file grep-i_acpi, and another one with the result of=
=20
dmesg | grep -i ACPI, in case you wanted to see when acpi appeared in the=20
bootup sequence. This second option is included in the attached file=20
dmesg_grep-i_ACPI

Attached is the file acpi_dsdt.dsl which gives no errors and no warnings.=20
Anyway, in this case, the WAK function includes the modification that I=20
added, returning a package with two zeros. This is different when I get the=
=20
asl file from acpidump. Do you think this can be the cause of the blockings?

I don't know what you mean by this. I thought that it finds the customized=
=20
DSDT because I applied a patch from http://gaugusch.at/kernel.shtml
in order to get the the customized dsdt from initrd. Otherwise it would use=
=20
the default one.
