Details - The GL.iNet GL-MT300A runs stable on LEDE 17.01.1.  This device is an ramips/mt7620 target.

However, two users in the LEDE forum have reported that the device becomes unstable after upgrading it to LEDE 17.01.2 or later (including 17.01.4).  The device boots but then crashes and reboots in a loop over and over.  The only workaround seems to be to go into recovery mode and then flash back to LEDE 17.01.1 after which it becomes stable again.

It's difficult to debug as you can ssh into the device upon boot, but then it crashes within a minute or two.  One user in the form post below suggested it is related to the Wi-Fi driver.
