SD CARD kernel panic error

Prakash A S
Hello all,
      I followed the steps from http://narnia.cs.ttu.edu/drupal/node/131
and tried to boot the GPE linux from SDCARD on Mini2440. All the steps went
fine. When I boot the linux from sdcard, I am getting so many error lines
like, 

Empty flash at 0x024cbffc ends at 0x024cc000
Empty flash at 0x024cfffc ends at 0x024d0000
......
..... and 

uncorrectable error : <4>mtd->read(0xa8 bytes from 0x262f58) returned ECC
error
.......
.......
and finally got, 
Kernel panic - not syncing: Attempted to kill init!

I have pasted my logfile here, http://pastebin.com/7RFhWPGF

Help me to boot the linux from SDCARD successfully. If we have any
reference for the issue, please let me know.

Thanks in Adv,
Prakash.
