Hi all, I built stable tree and latest(linus' tree) with default configuration and then installed them on my laptop. However, when I try to boot my system with kernels that I built, it cannot boot. It freezes just after selection made on GRUB and nothing is printed on the display. I managed to get following error by booting system in recovery mode: Starting up ... mount: mounting /dev/disk/by-uuid/48bfb57f-4750-4537-b563-7094743c161e on /root failed: Invalid argument mount: mounting /dev on /root/dev failed: No such file or directory mount: mounting /sys on /root/sys failed: No such file or directory mount: mounting /proc on /root/proc failed: No such file or directory Target filesystem doesn't have requested /sbin/init. No init found. Try passing init= bootarg. I build kernel with following commands: make O=../build defconfig make O=../build -j2 sudo make O=../build modules_install install You could see grub.cfg entries below for both (custom build kernel and stock build kernel): # Custom build menuentry 'Ubuntu, with Linux 3.2.7' --class ubuntu --class gnu-linux --class gnu --class os { recordfail set gfxpayload=$linux_gfx_mode insmod gzio insmod part_msdos insmod ext2 set root='(hd0,msdos3)' search --no-floppy --fs-uuid --set=root 48bfb57f-4750-4537-b563-7094743c161e linux /boot/vmlinuz-3.2.7 root=UUID=48bfb57f-4750-4537-b563-7094743c161e ro quiet splash vt.handoff=7 initrd /boot/initrd.img-3.2.7 } # Stock build menuentry 'Ubuntu, with Linux 3.0.0-16-generic' --class ubuntu --class gnu-linux --class gnu --class os { recordfail set gfxpayload=$linux_gfx_mode insmod gzio insmod part_msdos insmod ext2 set root='(hd0,msdos3)' search --no-floppy --fs-uuid --set=root 48bfb57f-4750-4537-b563-7094743c161e linux /boot/vmlinuz-3.0.0-16-generic root=UUID=48bfb57f-4750-4537-b563-7094743c161e ro quiet splash vt.handoff=7 initrd /boot/initrd.img-3.0.0-16-generic }
