kernel crashing with jffs2 (32MB NAND Flash and 32MB SDRAM )

Hi,
We are facing some memory issues with ATMEL AT91SAM9G20 Board.
By changing the uboot environment variable –bootargs
setenv bootargs console=ttyS0,115200 root=/dev/mtdblock2 rootfstype=jffs2 mem=8M
mem=8M
mem=16M
mem=24M
mem=32M
On changing the value of mem variable the boards behaves in different way.
At 8M,16M the Linux is coming up but after the kernel prompt it is
crashing in between.
At 32M-the Linux is not coming up over board. Before kernel prompt
it’s crashing.
The size of SDRAM is 32MB.but we are not able to utilize it fully.
Is it u-boot or Kernel or jffs2 or SDRAM problem?
Am updating below the kernel config as well as boot logs.
