Thread: Problems in upgrading kernel to 2.6.39.4

hi,

newbee in kernel compilation , trying upgrade lucid kernel "2.6.32-33-generic" "2.6.39.4".

compiled kernel default configuration i386 architecture, installed it, created initramfs same. grub.cfg looks below

menuentry 'ubuntu, linux 2.6.39.4-test' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 39abd5ae-5bae-4981-92c1-4e861748a0b3
linux /boot/vmlinuz-2.6.39.4-test root=uuid=39abd5ae-5bae-4981-92c1-4e861748a0b3 ro crashkernel=384m-2g:64m,2g-:128m quiet splash
initrd /boot/initrd.img-2.6.39.4-test
}
menuentry 'ubuntu, linux 2.6.39.4-test (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
insmod ext2
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 39abd5ae-5bae-4981-92c1-4e861748a0b3
echo 'loading linux 2.6.39.4-test ...'
linux /boot/vmlinuz-2.6.39.4-test root=uuid=39abd5ae-5bae-4981-92c1-4e861748a0b3 ro single
echo 'loading initial ramdisk ...'
initrd /boot/initrd.img-2.6.39.4-test
}
menuentry 'ubuntu, linux 2.6.32-33-generic' --class ubuntu --class gnu-linux --class gnu --class os {

initrd /boot/initrd.img-2.6.32-33-generic
}

when trying boot new kernel getting screen saying

a bit more context help. how options set when built kernel? see output of ls -l /boot? exact command used build initrd (e.g. history | grep initrd)?
