Supply the following if possible:

• Device problem occurs on
  Comfast CF-E5
• Software versions of OpenWrt/LEDE release, packages, etc.
  master
• Steps to reproduce
  Press the reset button, observe that nothing happens. We expect the device to reboot or perform factory reset.

I am on the latest master snapshot using a Comfast CF-E5. The reset button is supposed to be on GPIO17. I have an IRQ entry of gpio-ath79 17 on my system but when I press the button I can never see any response in the logs, and the device never responds to the key with either a reboot or firstboot. What can I check? It used to work on an older version. I have documented what I have found on the forum.
