Sir, After I got my avalon ten days ago I connect them with power and never touch them again. And, two avalon crash at the same time. I think it should be has nothing to do with internal connections.

Yes I totally understand that. However if you feel comfortable enough to double check the connections I would do so. You posted a Bus Error. This is something I would personally check myself. The error just leads that way.

BTW.. I have read about Avalons being bumped in shipping.. this is also why i would look into these things

its not your network when your showing something like this.

Yes. I think so.

 
Do you feel comfortable enough to open your unit and make sure the connections inside are good? I know there is a controller board and such that could have been bumped around in shipping. This is where I would start. And yes I know it was fine for 14 days. However, it could have had a good enough connection for now.. who knows.. but something to check

One thing I can think of that might cause both to fail at the same time that doesn't have to do with software is a power surge. I have no direct experience but I can imagine the power quality in China might not be the best. Surges from industrial equipment turning on can damage all electronics. The power supply in theory should provide some protection but not always. Do you live in an industrial area?

Sir,

I think it has nothing to do with power surge. Here is BeiJing China the power supply is quite stable.

And, we could see openwrt still running well inside of avalon.

And I still have other icarus running quite stable in the same room.

  • Start cgminer with your regular commands and add -D --verbose
Code:
cgminer -D --verbose -S /dev/ttyUSB0 -o http://us.ozco.in:8331 -O xxxxxx.0:yyyyy--avalon-options 115200:24:10:45:282

Since they're failing at the same time, I would actually think it's a software issue. Very unlikely that hardware would fail at the same time. However, if it's software, the same problem could happen to both machines at the same time.

I think so. But, the strange thing is that, I restarted cgminer several times, and I rebooted avalon several times, and, I changed mining pools too.  So, not easy to understand.

In list of things to try:
  • Can you try connecting them via a different network, like wireless to your laptop and then VPN or something.

Jgzarik.. Hows your Avalon?
Can you say in red that you don't have an Avalon.  Grin

I have to mention 2 avalon because they crash at the very same time. I feel it quite abnormal.

...

I am afraid it is hardware related issue.

Things to try
  • Get the latest firmware from jgarzik or some other Avalon customer who downloaded it
  • Check if it's related to change in difficulty. Are you mining with stratum and high enough difficulty?

Same time different rooms, maybe network issue? Don't they come with a static ip? Perhaps they are trying to use the same address? Maybe try running only one of them. Or, send one to my house and I'll let you know if it still works.

Firmware question:
Did you get the firmware update that jgarzik got?


doesn't look like it. he is on cgminer 2.10.4.

ATX power supplies always provide power on some of their rails unless they're physically disconnected or have a hard switch. So I really hope this is just a hardware controller hanging (inconsistent state cleared by power reset) or something like that.

Sir, I unplug power cable from wall and plug it again after a while. Nothing help.
What temperature is the room at when you ran the devices?

You had 2 working avalon for 14 days and thought was not worth

I have to mention 2 avalon because they crash at the very same time. I feel it quite abnormal.


anyways, a bus error might indicate a core dump due to many reasons, a change in data supplied (increase in difficulty to 4*10ˆ6) or over heating

I am afraid it is hardware related issue.


Can you point it to another pool?

Sure. I mentioned it. I tested them with ozco nothing different.


Turn one machine off and let it cool down for an hour?

Yes.


What does dmesg give you as unusual errors?

Nothing useful. Seems avalon does not output error message to system log.
