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 Signed-off-by: oliver@opencloud.com SVN-Revision: 9666
