RE: Gentoo on Acer Aspire 3502WLCi with bugged DSDT (Phoenix BIOS)

[Fabio Venturi <fabio.venturi@studenti.unipr.it>]

Thank you for the answer ,
as i wrote, i already downloaded (from the ACPI site)
and compiled with iasl a bug-fixed DSDT for my laptop,
the problem is I can't make the kernel read it during the boot.
In a gentoo forum (http://forums.gentoo.org/viewtopic.php?t=122145)
i found that i can pass the new DSDT.aml to the kernel
like an initrd image so i changes grub.conf like this:

[...]
title Gentoo GNU/Linux (Fixed DSDT)
kernel (hd0,2)/boot/bzImage-2.6.15 root=/dev/hda3
initrd=(hd0,2)/boot/DSDT.aml
[...]

but when the system finish to boot, "dmsg |grep -i dsdt" says:

ACPI: DSDT (v001 PTLTD     661MX 0x06040000 MSFT 0x0100000e) @
0x00000000
ACPI: Looking for DSDT in initramfs... error, file /DSDT.aml not found.
Table [DSDT](id 0006) - 485 Objects with 39 Devices 93 Methods 10
Regions

So the original DSDT from the BIOS is loaded instead of
loading the custom one.
(Yes, i activate the CONFIG_ACPI_CUSTOM_DSDT, RamDisk Support ecc..
options)
I hope I clearly explained my problem (in a bad english :oP ),
thank you for this and any further help
regards
Fabio
