#19329: ar71xx/wndr3700 in reboot loop at r45064
--------------------------+----------------------------------
Reporter: hnyman | Owner: developers
Type: defect | Status: new
Priority: high | Milestone: Chaos Calmer (trunk)
Component: base system | Version: Trunk
Resolution: | Keywords: reboot loop
--------------------------+----------------------------------
Comment (by hnyman):
I sacrificed my space 3700v2 and flashed the problematic r45064 to it and
attached a serial cable. The router first booted up ok, as there was no
wifi settings.
After applyting my normal settings, it still seemed to be ok maybe about
50 seconds. But as soon as I tried to initiate wifi contact from my
tablet, the router crashed:
