mount :could not find file system '/dev/root'
 

Hi All,

I am a newbie to Linux kernel configuration. I have configured the kernel 2.6.18 and planning to boot the kernel along with the initrd image on QEMU(hardware emulator).But i get this kind of error which is shown below.

Please inform how to resolve this issue ASAP :)
Any help would be greatly appreciated

Thanks.

Something is missing from your initrd - driver for disk, or the filesystem support. Personally I build as much as possible into the kernel itself to avoid these sort of issues - don't know how that might impact on embedded.

Thanks for the reply.
But i am using a CentOS distro to create the kernel and initrd image 2.6.18.

Right now i do not have a target board to test the test the image.Hence i am using QEMU.

Which are the modules do u think should be added to the kernel to overcome this errors?
What is the procedure you follow to create initrd image ?
Please throw some more light on ur last reply.
