hi all,
I've had an avalon 741 running for a long time now without any problems. I had a few power cuts recently, one after another because the sub station was having issues for my road.

Because of the power cuts this seemed to corrupt the sd card in the controller and i had to buy a new one. I re flashed the OS onto the card just like normal.

But ever since then my asic stops showing up on the pool. when i login to the controller via a browser i can see the OS is still running but its not connected to the pool and obviously its not hashing either. I perform a reboot and it all starts working again straight away.

it does this every couple of days.

any ideas guys?
thanks
zac
