Linux kernel panic

Question

While booting linux, i'm getting following prints on console, and the system hangs.

Waiting for root device /dev/mmcblk0p2...

I think it's due to some incorrect boot arguments.

How to solve it?

What is wrong here? (I'm booting from MMC ) How i can correct this error?

Answer 1

I think the file system is unknown to the system.

Try changing the file system on MMC to ext3 / NTFS .
