Regarding of this conflicts open bug-report
https://bugzilla.redhat.com/show_bug.cgi?id=470479
https://bugzilla.kernel.org/show_bug.cgi?id=12376 many times it is found in the
mailing lists http://markmail.org/message/jxcsqw5aw2y7keno
So at the moment I'm using current unstable gentoo linux(output emerge --info
in the file "emerge-info") with kernel 2.6.38.6 with some patches from
fedora-linux (A list of patches in the file "patch_list" And the patches
themselves can be found here
https://github.com/init6/init_6/tree/master/sys-kernel/fc-sources/files/2.6.38.6
or here http://pkgs.fedoraproject.org/gitweb/?p=kernel.git;a=tree ).
Kernel installed by ebuild
https://github.com/init6/init_6/raw/master/sys-kernel/fc-sources/fc-sources-2.6.38.6.ebuild
Kernel config in file "kernel-2.6.38.6-fc-config".
File "acer-aspire-5730zg-bios.v-1.23-original.dsdt" - original uncorrected dsdt
from my laptop http://ru.gentoo-wiki.com/wiki/Acer_Aspire_5730ZG
The same kernel - 2.6.38.6. One and the same system. Kernel compiled with the
same configuration file. Differences only in dsdt.
Two directories "vanilla" and "fixed".
In "vanilla" bug fixes the file "acer-aspire-5730zg-bios.v-1.23-original.dsdt"
No changes just bug fixes.
In the "fixed" as a basis, I used file "dsdt.dsl" from the "vanilla" but made
too many changes and hacks ... Something of these changes have worked.
And now with the kernel on fixed-dsdt conflict disappeared!
