Did issue begin when the difficulty recently readjusted, perhaps?
You might try mining on testnet and see if that behaves any differently.
I'm not sure how much a pool hides the network difficulty from a miner. cgminer somehow seems to always know the network difficulty and display it for me regardless of what pool I use.

[2013-03-02 04:02:40] New block: 00fb4966084a69b4... diff 18.4E
Bus error
18.4E is 18.4 * 10^18. This also happens to be the maximum value of a 64 bit unsigned int. That is not the correct difficulty.
The bus error suggests an attempt to read from memory outside the real range.
Both of these point to some kind of memory corruption issue, which is either a cgminer bug (not very likely) or a bug in the avalon driver (quite likely). (A hardware error on the control board is also possible, but unlikely on two independent devices.)

If I am not mistaken a Bus error is the same as a Segmentation fault.

This is what happens when ya forgot to update.....
March 01, 2013, 09:32:03 PM
And the remaining window fro GPU mining got some fraction wider. Good thing I didn't turn off back in October when they told me the sky was falling.

Crashed within one second each one another from 2 different locations and also certainly with 2 different running times... Dosent make any freaking sense. How far way where the locations from each other?
Since that its a "modular design" and that you get a bus error, have you tried disconnecting some of the modules and boot with only one or 2 module?
Maybe the pool sent a "share of death" that killed your hardware. How funny would that be? (Sorry for the joke)

Did you change anything? Is there free space?
March 01, 2013, 08:48:08 PM
You might also try the firmware update.
Ok. I have emailed them for latest firmware.
March 01, 2013, 08:25:07 PM
How about open the case and upload some pictures to see if there's something obvious?

Sir, I opened avalon case and reconnected all connections cables. But, seems nothing helpful:
Damn.. now i am bummed for ya. I was almost certain this to be the case. Hopefully BitSyncom will be on this evening if not tomorrow morning.

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.
March 01, 2013, 07:39:20 PM
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
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.
Thinking it should be, is different that checking. Please make sure all the cables are properly seated.

March 01, 2013, 07:35:32 PM
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.
