 |
|
I've recompiled the kernel linux. I've only added some options for power saving, and wireless support.
That, i've re-run "grub-install /dev/sda" and "grub2-mkconfig -o /boot/grub/grub.cfg". (I don't know if that was neccessary).
Now I can't run Gentoo, (I can't also in recovery mode). I made a screenshot. Here the computer is blocked... and I see that the led of the "mascius shift" is blinking.

In Grub I can load an other item from the list . (Gentoo 3.12.20 which is the same version of the kernel .... but i think with the previous configuration). And this version runs correctly. |

The panic picture seems to suggest that graphics support is misconfigured. What graphics card(s) are installed and what video driver(s) are you trying to use?
sys-kernel/gentoo-sources-3.12.21-r1 is the current stable version according to http://packages.gentoo.org/package/sys-kernel/gentoo-sources. Suggest booting the working kernel, then running:
(assuming you use a manual kernel) | Code: | emerge gentoo-sources
eselect kernel list
eselect kernel set linux-3.12.21-gentoo-r1
# or eselect kernel set {the number assigned linux-3.12.21-gentoo-r1}
cd /usr/src/linux
zcat /proc/config.gz > /usr/src/linux/.config
make oldconfig && make menuconfig
make && make modules_install && make install
grub2-mkconfig -o /boot/grub/grub.cfg
reboot |
(assuming you use genkernel) | Code: | emerge gentoo-sources
eselect kernel list
eselect kernel set linux-3.12.21-gentoo-r1
# or eselect kernel set {the number assigned linux-3.12.21-gentoo-r1}
cd /usr/src/linux
zcat /proc/config.gz > /usr/src/linux/.config
genkernel --oldconfig --no-mrproper --no-clean all
grub2-mkconfig -o /boot/grub/grub.cfg
reboot |
assuming the new kernel boots, add the options for power saving and wireless support a little at a time, technique for manual kernel is normal, for genkernel use "genkernel --no-mrproper --no-clean --menuconfig all"

What're you talking about? The stacktrace seems to suggest a timer problem. But do note that the really interesting stacktrace is the one that's scrolled offscreen. mrfabiolo, could you perhaps boot with vga=ask and select a higher resolution than your framebuffer is currently using? |
