[ELDK] Kernel panic with suspend/resume

[liudan]

Hi,
I get the kernel source(DENX-v2.6.38-stable) from http://git.denx.de/?p=linux-2.6-denx.git, and configure it for AMCC40X. When I implement suspend(on swap partition) and reboot the system, the kernel panic occured with resume.
Error info:

Kernel panic - not syncing: kernel stack overflow

The file attached is the kernel's config. I was puzzled with error two weeks. How can I fix the error? 
Any reply would be appreciate!
