I tested uPD720200"A" again with clean 3.1-rc3, the speed will be changed after every reboot: after 1st reboot: 480 after 2nd reboot: 5000 3rd: 480 4th: 5000 uPD720200"A" + clean 3.1-rc3 + 0001-xhci-Set-change-bit-when-warm-reset-change-is-set.patch: not work, the same symptom. uPD720200 + clean 3.1-rc3: no problem, always 5000 at 4 times reboot. It seems the NEC firmware's issue, I will report to NEC FAE, thanks for your help2.
