initramfs and kernel 2.6.7

initramfs and kernel 2.6.7

[Arkadiusz Patyk]

Hi,

I 'am trying to launch linux kernel 2.6.7 with initramfs.

My pxelinux.cfg/default file looks as follows:
default a1
prompt 1
timeout 600
label a1
kernel vmlinuz-2.6.7-1
append initrd=initramfs_data.cpio.gz root=/dev/ram0 init=/linuxrc

Kernel image  vmlinuz-2.6.7-1 and  initramfs_data.cpio.gz was loaded 
succesfully by pxelinux.

Kernel says:
checking if image is initramfs... it is

but later occurs an error:
Kernel panic: VFS: Unable to mount root fs on ram0

Full log: http://rescuecd.pld-linux.org/minicom.cap

What should I do to run my system? 
Maybe root=/dev/ram0 is not correct?

Best regards,
--

The append line is unnecessary

First, your script with your initramfs should be called init and
not linuxrc :-(

Assuming that you are creating the cpio with --format=newc,
you should copy your initramfs.cpio.gz to:
linux-2.6.7/usr/initramfs_data.cpio.gz

Make the kernel, boot the kernel; and the initramfs will be mounted as
root, and control given to the init script.
