Felix, We think this is an SOC level problem given the at803x and defect is embedded in the AR93xx SOC. This GPIO pin is believed to be in silicon. If so, the same GPIO across all hardware that uses this SOC. Specifically, for the Ubiquiti "AirMax" line, this SOC is relevant to:
AirGrid HP M5 XW NanoBridge M5 XW 16/19 NanoStation M5 Loco XW PowerBeam M2 XW 400 PowerBeam M5 XW 300/400 PowerBeam M5 XW 620 (Rocket XW image but has newer flash chip and needs write protect fix still) Rocket M5 XW Rocket Titanium M5 XW (for completeness, but we're not supporting this) NanoStation M5 XW (this has an external switch chip somehow avoiding the defect or other). We have only been able to reproduce this failure on NanoBridge M5 XW 19 and the Loco NS M5 XW (in CC release). A ~year ago the symptoms occurred in CC builds in all models except NSM5-XW. Presumably, you had since committed a fix within the at803x driver for the ubnt devices that appear to be working now? Regardless, all these devices are in scope (as could be other manufacturer's devices) to be included in the fix at the SOC level. Will the Lede staged commit catch all these devices?
