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

[libertybuck]

Today morning I login btcguild to check my avalon. To my surprise I find both of my avalon IDLE there with mining speed 0.  



I am not sure what happened so I login openwrt console and run the following command:

Code:

root@OpenWrt:~# /etc/init.d/cgminer stop
no cgminer found; none killed

Code:

root@OpenWrt:~# 
root@OpenWrt:~# /etc/init.d/cgminer start

And then I run ps command still could not find cgminer running.

I am not sure if it has relation with btcguild pool so I change pool to ozco and run the above commands again. Still nothing luck.


Now, I run the following command:

Code:

root@OpenWrt:~# cgminer -S /dev/ttyUSB0 -o http://us.ozco.in:8331 -O xxxxxx.0:yyyyy--avalon-options 115200:24:10:45:282
 [2013-03-01 22:47:22] Started cgminer 2.10.4                    
 [2013-03-01 22:47:22] Avalon: Reset succeeded                    
 [2013-03-01 22:47:22] Probing for an alive pool                    
 Bus error

root@OpenWrt:~# 

Base on the above fact I am afraid both of my two avalon are broken.
How stange it is !  
Both of them broken at the same time !
My avalons run well for the past 14 days and then crash at the same time !

Any one could understand it ?

Because I fail to contact nzhang via email and phone call so I have to post topic here.  

YiFu, nzhang, xiangfu, anyone of your three please contact with me via phone call or email I will prepare teamviewer for you with it you could login my avalon to have a check.

Urget help needed!

You one of the Chinese custormers, right?

Silly of me to ask maybe, but have you tried turning it off and on again? Did you get the firmware update that jgarzik got?

[darkip]

Unlikely both have failed at exactly the same time. More likely is you started them at the same time and some sort of memory leak / OS error is causing this. I expect a restart will probably fix the problem.

[kaerf]

check the cable connections inside the box too

[libertybuck]

You one of the Chinese custormers, right?

Yes.

have you tried turning it off and on again?

Sure.  I tried reboot command under openwrt console several times. Each time after avalon rebooted with ps command I could find cgminer dispear soon.

[Beepbop]

Do you not have physical access, or a remote controlled PDU? Sometimes hard reset (power off, and on again) might be needed.

[libertybuck]

Sir, I run them at 14 days before at the same time. And based on the above btcguild picture we could see they do not mine at the same time.

I just restarted them many times nothing turns good.

[libertybuck]

Sir, they are two avalon located in different rooms. No one touch them because they are all working well last night before I went to sleep.

You had 2 working avalon for 14 days and thought was not worth just mentioning that in the relevant threads where people are begging for delivery info? Wow... that is going to score karma points...

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

Can you point it to another pool? Turn one machine off and let it cool down for an hour?

What does dmesg give you as unusual errors?

[libertybuck]

Nothing.  Anyway I will unplug power cable and plug it again to have a check now.

[Beepbop]

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.

[darkip]

Hopefully this is not related to the comment in their most recent email:

Lessons learned. Batch #2 process will have improvements, minor design adjustments and other goodies.

[libertybuck]

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.

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.

Sir, I unplug power cable from wall and plug it again after a while. Nothing help.

Firmware question:

Did you get the firmware update that jgarzik got?

What temperature is the room at when you ran the devices?

[kaerf]

Firmware question:

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

[CrazyGuy]

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.

[Beepbop]

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?

...

I am afraid it is hardware related issue.

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.
