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:

I was puzzled with error two weeks. How can I fix the error? Any reply would be appreciate! 2011-10-25 liudan
