Hang in inflate_dynamic() mpc8321

Hi All,

Iam working on the new board bringup of linux ppc image on 2.6.24 using the
powerpc mpc832x. I used the file system image (based on the initrd ram disk
image), dtb file(generated by the dtc compiler for our mpc832x_rdb.dts) and
the kernel powepc compiled.

Iam facing a hang up in the booting in the call inflate_dynamic() from the
gunzip() function. Initially I suspected it could be RAM issues, and I
performed the simple RAM test (mtest) from the bootloader and it went
through succesfully.

Below is the log message observed in the system booting stuck at
"checking if image is initramfs..."

Please let me know what could be the problem.
