Kernel without initramfs hang at boot

[ser]

Kernel configuration (that i'd always used) in a new installation of Funtoo 1.4 hang at boot: the system freeze after message "random: fast init done". To solve it i must use initramfs

The same kernel configuration work well (without initramfs) in any other installation of Funtoo/Gentoo: for example, in my old installation of Funtoo, updated to 1.4 release, the kernel normally boot without initramfs.

I search on web but i don't find what's the problem.

Respond myself to the question.

I don't know why, but for boot Funtoo without initramfs must be set CONFIG_DEVTMPFS_MOUNT=y.

In Gentoo succesful boot without initramfs with  CONFIG_DEVTMPFS_MOUNT not set.
