Hello All, 

I am porting linux-2.4.22 to MPC852T based board. I
have an issue with the Ramdisk. I have a total of 64MB
SDRAM, and I am creating a ramdisk of 32MB. The
compressed Ramdisk file is of 3.4MB size. Look like
when I do the "bootm" command the Ramdisk is
corrupting some important u-boot data. I have the
console dump below. 

Is there a minimal Ramdisk that I can directly use ??

Warm Regards
Raghu.
