Minor patch to the AR7 diag.sh to make the status LED a bit more useful. From the patch:
This setup gives us 3.5 distinguishable states:
- Solid OFF: Bootloader running, or kernel hung (timer task stalled)
- Solid ON: Kernel hung (timer task stalled)
- 5Hz blink: preinit
- Heartbeat: normal operation
