I have Arch Linux running on a Cubieboard2 with a 500GB SATA drive attached. The power supply claims to be 5v @ 2.6A. I use it for a simple nfs file server.
Normally I see a blue double-blink about once per second. Twice now in the morning the device has been unresponsive and the double-blinks are more than twice as fast. What does it mean, other than the generic "a problem has occurred"?
I cannot get in via ssh to see logfiles or otherwise see what is happening. I use a wired connection. I get either 'no route to host' or 'connection refused'. This occurrs whether the disk is attached or not.
Where do I look next?
Thanks
