Arch Linux

hello.

i upgrade the version of following packages:
core/linux 4.3.3-2
extra/nvidia-304xx 304.131-3
community/virtualbox-host-modules 5.0.12-2

in this upgrade with "pacman -Syu" crash the kernel and nvidia. The nvidia driver giveme with this error log and not load in the memory:
nvidia: Unknown symbol mtrr_del (err 0)
nvidia: Unknown symbol mtrr_add (err 0)

with this error not create the /dev/dri/card0 and can't execute the Xorg.

I view this bug page in https://bugs.archlinux.org/task/47092, and try fixed this error using ABS for apply the new patch:

modify in PKGBUILD for add two new lines to source= and prepare() for apply the new patch, make new gpg keys with "makepkg -g", take the output and replace the sha256sums= in the PKGBUILD, compiling with "makepkg" (trying again after of added with gpg keys for linux-4.3.tar.xz and patch-4.3.3.xz), and install with "makepkg -i".

i have this change in PKGBUILD:

now the error output of dmesg is:
nvidia: no symbol version for mtrr_del
nvidia: Unknown symbol mtrr_del (err -22)
nvidia: no symbol version for mtrr_add
nvidia: Unknown symbol mtrr_add (err -22)

I not have most idea for fixed....

Try install with linux-lts, not have change in the kernel (the lts is 4.1.15 but i always having with 4.3.3)

Then install the old packages that i have in the cache of pacman.

now have this in the system:
core/linux 4.3.3-2 (base) [instalado: 4.2.5-1]
extra/nvidia-304xx 304.131-3 [instalado: 304.131-2.1]
community/virtualbox-host-modules 5.0.12-2 [instalado: 5.0.10-2.1] <-- only for pass the dependences packages

the file /proc/kallsyms have:
[address] T mtrr_add
[address] T mtrr_del

Only the new version of kernel and nvidia have error with mtrr_add() and mtrr_del().

I have the GeoForce 6200 and only function with nvidia-304xx.
