"Javitasi" lepesek:
Ki kell nyerni a dsdt tablat az acpi-bol, es "visszafejteni" iasl-lel:
cat /proc/acpi/dsdt ~/dsdt
iasl -d ~/dsdt

Majd ujra leforditani:
iasl -tc ~/dsdt.dsl

Kapunk ket hibat:

dsdt.dsl   961:                     Release (LCK2)
Warning  1100 -        Statement is unreachable ^

dsdt.dsl  1136:             Return (0x04)
Error    4080 -                        ^ Invalid object type for reserved name (

Az elobbi ugy javithato, hogy a Return parancsot a Release utanra rakjuk a 961. sorban.
Az utobbi meg ezzel a sorral:

Return (Or (SUPP, 0x04))

Ezutan mar hiba nelkul lefut:

Compilation complete. 0 Errors, 0 Warnings, 0 Remarks, 21 Optimizations

Sajnos a kernelbol kiszedtek, hogy a dsdt-t initrd-bol is be lehessen tolteni, de szerencsere a grub2 is tudja ezt:

wget -O /etc/grub.d/01_acpi http://blog.michael.kuron-germany.de/wp-content/uploads/2011/03/01_acpi.txt
chmod +x /etc/grub.d/01_acpi

masoljuk a kesz dsdt.aml fajlt a /boot-ba, majd futtassuk az upgrade-grub-ot.

egy reboot utan a grub betolti nekunk ezt a fajlt, es mar nem lesz hiba a acpi tablaban:
