Kexec couldn't reboot capture kernel on pandaboard ES with OMAP4460

[Li Haifeng]

Hi, everyone.

Recently, I try to run kdump on pandaboard ES with omap4460. After
load capture kernel by "kexec -l" and execute "kexec -e", the serial
port output "Starting new kernel" and "Bye", then the system hangs up.

I have tried the upstream Linux Kernel v3.4 and v3.8. All are with this issue.

Could you tell my why and how to solve this issue?

Thanks very much.
