Description peterm 2000-06-28 00:30:25 UTC 
Kernel 2.2.12-20smp will boot up fine as will other 2.2.12smp kernels
I have compiled for my RedHat 6.1 box.

However, on trying to compile my own new 2.2.16smp kernel,
I get this error:
Kernel panic: No init found, Try passing init=option to kernel

I've also tried booting with
init=/sbin/init root=/dev/sda1

My new 2.2.16smp kernel has ext2 support, SCSI support both for hard disks
and for the Adaptec controller, and boot messages indicate that these
devices are recognized OK and that the partitions are seen(sda1 sda2 sda3
sda4)

Here is linux.conf:  "linuxold" and "linux-up" boot, "linux" won't.

boot=/dev/sda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
default=linux
linear

image=/vmlinuz
        label=linux
        APPEND="ether=0,0,0x30,eth0"
        root=/dev/sda1
        read-only
image=/boot/vmlinuz-2.2.12-20smp
        label=linuxold
        initrd=/boot/initrd-2.2.12-20smp.img
        read-only
        APPEND="ether=0,0,0x30,eth0"
        root=/dev/sda1
image=/boot/vmlinuz-2.2.12-20
        label=linux-up
        initrd=/boot/initrd-2.2.12-20.img
        read-only
        root=/dev/sda1

You need an inital ram disk when your root resides on a SCSI disk.  Try adding
the line:

initrd=/boot/initrd-2.2.12-20smp.img

to the "linux" entry of /etc/lilo.conf.  Then rerun lilo and reboot.
