Boot process doesn't decompress kernel

infern0 · 07-27-2014, 06:27 PM

Hi,
After choose entry from grub menu, it shows only "Booting a command list" and freezes(no errors, ctrl-alt-del not work, nothink)
Screen: http://gyazo.com/75f2aa71bfdeef8277ab862e9caaa6fc
System(gentoo) started under qemu. Kernel is maked from make allnoconfig and with very few options(for vda, running ELF binaries, ext4 and some options for gentoo qemu guest). Kernel sources: sys-kernel/hardened-sources

What causes this issue? Any help is welcomed. Thanx

cd to your kernel source and grep your .config file.

Code:

grep CONFIG_HAVE_KERNEL .config

tells you what capability for dealing with compression is built in to the kernel

Code:

grep CONFIG_KERNEL .config

tells you how it is stored
It needs the capability to unzip how it is stored, but 'make allnoconfig' doesn't think of things like that. I feel sure that option is for developers and embedded, not ordinary mortals.
