[FIXED] Avalon URGENT ISSUE: both of my avalon do not work any more

[Beepbop]

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.  

[libertybuck]

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.

[Bogart]

Plz post the results of these commands:

ifconfig

route -n

cat /etc/resolv.conf

ping -nc5 4.2.2.2

[Beepbop]

• 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

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?

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.

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.

its not your network when your showing something like this.

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

[libertybuck]

Yes. I think so.

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

Sir, I agree with your idea. I will try to open the avalon case and check it now.

[Dalkore]

Yes. I think so.

Thinking it should be, is different that checking.  Please make sure all the cables are properly seated.

[DrGuns4Hands]

Figured I'd share an odd story about connections. I'm an auto mechanic and worked on a 14 year old van the other day We've been working on it since it was new. The drivers window stopped working so I went to the switch to check it out and the switch wasn't plugged in. That door had never been apart before it must have not been plugged in fully by the factory and came loose over time. Plugged it in and has been working fine since. Connections can be oddly fickle.

[libertybuck]

Sir, I opened avalon case and reconnected all connections cables. But, seems nothing helpful:
