I have tried to set the kernel parameter idle=poll in the grub file. But it failed to boot again due to the same error. Could anyone help me to solve the problem? The full console output is attached. Thanks.

Do you know what version kernel works well between 2.6.32 and 2.6.39
in your machine?
As I look further, some culprit are 21a3c96468[memcg: allocate memory
cgroup structures in local nodes], 6cfddb26155[page_cgroup: reduce
allocation overhead for page_cgroup array for CONFIG_SPARSEMEM] if the
problem happen recently.
If kernel panic still happen, could you do git-bisect?
