Hi, noapic is not a too sophisticated solution. Try this:
mkdir bios_sck cd bios_sck sudo acpidump -b A lot of firmware file should be appeared we need SSDT/DSDT dat files You should decompile all of them but that is impossible because of some interference between the files. This combination worked for me: iasl -da ssdt1.dat ssdt2.dat ssdt3.dat ssdt4.dat ssdt5.dat ssdt6.dat ssdt8.dat ssdt11.dat ssdt13.dat ssdt16.dat ssdt18.dat ssdt20.dat dsdt.dat Ok, you have now a lot of dsl and you should recompile them iasl -tc *.dsl If you don't get any errors then you are very lucky but you will get some. So you should fix the errors in dsl files and try to recompile them again. Warnings are not important. How can you fix the errors? I don't know. Nobody knows beside of some GURUs. They have the proper energy and knowledge to fix them. Just go to the kernel bugzilla and ask the gurus. I wish you luck son. If you are lucky enough and get what you need (you won't), came back and I will tell you what to do next.
