The problem has been fixed. It is the conflict between TLP and bumblebee that causes the problem. Although I had included PCI "01:00.00" in tlp's pci blacklist, tlp still holds the control of nvidia graphic card's power management.

After I add "pcie_port_pm=off" in kernel options the problem suddenly disappeared.

Plz set this bug thread as invalid since this is a problem between tlp and the linux kernel.
