Kernel boot panic

[Amit Mahadik]

Hi Kristof,              Yes I tried mounting the SD card on another Linux machine. I can mount it. Following is its log*********************************************************************************************************************************************************************************root at sagark-Ubu14:~/amitm# mount

I have created the ROOTFS image using buildroot 2016.05 version. The /dev management option selected is "Dynamic using devtmpfs + eudev" and corresponding DEVTMPS options are enabled in Kernel config. 

Browsing through the kernel code I find that the code gives error after create_dev API in init/do_mounts.c file. 

Please let me know what I am doing wrong or missing?
Regards,Amit.

Have you tried mounting the ext3 partition in another linux machine?  
Your log
indicates the kernel is not able to mount the partition, so the most 
likely
causes are that the kernel doesn’t know how to read ext3 or that 
there’s no
ext3 there.

Regards,
Kristof
