Hi Andrei,

I'm porting Sigma EM85XX patches from 2.4.17 to 2.6.24 kernel. The

CONFIG_SERIAL_JASPER=y
CONFIG_SERIAL_JASPER_CONSOLE=y
CONFIG_SERIAL_JASPER_SERIAL_BAUDRATE=38400
and uses serial console during boot (console=ttyS0). I can see all
boot messages until the warning "unable to open an initial console",
but then only errors are displayed. My init script in the intiramfs
looks like:
mount -t proc proc /proc
mount -t sysfs sysfs /sys
busybox --install -s
mknod /dev/null c 1 3
mknod /dev/console c 5 1
mdev -s
exec sh
and etc/inittab has a line
::respawn:getty -L ttyS0 38400
^^^^^
Do you have a /dev/ttyS0 device in your root fs?

Greg
I've added debug output to exec() and can see that the commands are
executed
exec: (/init) /init | exec code: 0
exec: (/bin/sh) mount -t proc proc /proc | exec code: 0
exec: (/bin/sh) mount -t sysfs sysfs /sys | exec code: 0
exec: (busybox) busybox --install -s | exec failed code -2
exec: (/bin/busybox) busybox --install -s | exec code: 0
exec: (/bin/sh) mknod /dev/null c 1 3 | exec code: 0
exec: (/bin/sh) mknod /dev/console c 5 1 | exec code: 0
exec: (/bin/sh) mdev -s | exec code: 0
exec: (/bin/sh) sh | exec code: 0
but it results in
Kernel panic - not syncing: Attempted to kill init!
Any ideas what I did wrong?
