[RB-050/RB-100/RB-110] Kernel Panic problem

[gdo]

Hello,

I have a kernel panic occuring at boot just before /sbin/init to be launched.
To build my system, I use my script from there : http://robosavvy.com/forum/viewtopic.php?t=8011

Linux generic kernel from Ubuntu is working so I think it is due to the Roboard kernel configuration, but I cannot find what is missing...

If someone could tell me if he can reproduce or not on other roboard it would be very helpful.

Here is the trace :

Hi gdo,

The problem is caused by our kernel package is lack of some scripts that could automatically generate initramfs file for corresponding kernel, so the kenrel will not find the device node of root filesystem when booting.

We suggest that you could modify your script as follows:
