[gentoo-user] Kernel Problems - Reboot on Load

[Loopingz]

I'm a newbie on Gentoo, i've made the installation from stage 1, compile everything and when i reboot the system, i see Grub then when i choose to load the linux, it seems to load the kernel, but the screen go black and after 2 seconds the system is rebooting. I think it's a kernel compilation problem but i don't know the solution.   Thanks for helping   Loopingz
