I noticed I didn't have any zombie mode since I changed my TV to another group, I also noticed in retrospect, that the zombie mode happened after I turned on an electrical device that was attached to the same group, have been running smooth now for 16 days (10 days of cgminer uptime, 16 days of device uptime) .. but i'm not sure if that is because I changed the TV, but who knows..
A fridge, a washing machine, a dishwasher, hairdryer, air conditioning - all such devices being plugged in the same house wire with the Avalon could easily make it feel dizzy, as well. So better take it into account and/or think about the stock PSU upgrade. |

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

When you reset, somehow, it should go back to default, which is, accordinly to the avalon user guide: 192.168.0.100 Well that worked..almost. I could enter failsafe-mode. Here's the instruction: -- To get into failsafe mode, power up the device and wait until the LED starts flashing (about 2Hz). Once it starts flashing (within about 4 seconds) then quickly press the button. The LED will then flash much faster and the device will be in failsafe mode. -- Failsafe IP is 192.168.1.1. I could telnet to the router. I checked root@(none):/# cat /etc/config/network config 'interface' 'loopback' option 'ifname' 'lo' option 'proto' 'static' option 'ipaddr' '127.0.0.1' option 'netmask' '255.0.0.0' config 'interface' 'lan' option 'ifname' 'eth0' option 'type' 'bridge' option 'proto' 'static' option 'netmask' '255.255.255.0' option 'ipaddr' '192.168.0.100' option 'gateway' '192.168.0.1' option 'dns' '8.8.8.8' Everything seems fine. Anyway, after rebooting I'm not able to ping or ssh 192.168.0.100. Edit: Fixed it! After making the filesystem writeable with "mount_root" /etc/config/network looked differently: config interface 'lan' option ifname 'eth0' option type 'bridge' option proto 'static' option ipaddr '192.168.0.100' option dns '8.8.8.8' option gateway '192.168.0.101' option netmask '0.0.0.0'Changed it. Reboot. Problem solved. (And back to my original problem. Will probably talk about that later..) Thanks for your great and fast help! |

Done a little bit study about the cooling, after adding two nexus real silent fan at exhaust, this is the profile I get from a script which recorded the temp each half an hour for several days  After ambient temperature reached 20C, both fan3 and temp3 start to accelerate upwards, means cooling effect start to drop. I have not tested the temp1 at higher than 26C, but I suppose that after the fan reaches 3000+ RPM and temp3 being higher than 47C, the noise and the module temp will become unacceptable I'm considering two options: Use an air conditioner to keep the intake below 20C, or underclock the avalon when temp3 is higher than 45 degree Another option is to take all the modules out and mount the cooling fan directly on the heatsink, like someone's cooling on BlockErupter blades, I believe this will dramatically reduce the temp3 by at least 5 degree, but then the other side of the module also need to be actively cooled, it will need at least 3 fans for each module and 9 fans for all 3 modules...  The existing fans in avalon are industry grade server fans, works quite well, but the datacable and powercable all blocked part of the air that flow through the heatsink |

My avalon clocked at 300 making 71 GH steady was ok at about 30C ambient for three days in a row. However that was for three days only. I have air conditioner now and ambient is at 23C. I do really think that at 35C it will be OK as ngzhang stated but i am not going to try it anyway  |

I am using firmware 20130419. Unfortunately, I don't recall the previous firmware version I was using.
Prior to the upgrade on May 5, the Avalon unit ran without any problems.
However, after the upgrade, the miner has stopped hashing twice, and the only way to recover is with a cold reset. Is this a know issue?
Cheers!

Yes, it seems there are a few race conditions that can present themselves putting the PDU into an inconsistent state. The end result is that all the values it gives out are 0 (see the screenshot I posted a week ago) The only solution is to do a hard reset The cause is probably related to mains net pollution. This could be a high power device like an airco switching on and off on the same circuit on your fuse box. Perhaps the spike only presents itself once a while and that is why you did not notice until now. It does not look to be software related. Perhaps batch #2 and batch #3 will ship with a different design (some difference appear from the released diagrams) Try to clean up your mains net as much as possible to play safe |

Perhaps the spike only presents itself once a while and that is why you did not notice until now. It does not look to be software related. I don't know what "mains net pollution" is  The power going into my unit is VERY clean and isolated from all other loads. (think data center) I'm tempted to go back to a previous firmware because the extra 2GH/s benefit is lost when the unit stops hashing. |

If anyone has problems, I have a new firmware you can try. PM me for a link.
Based off cgminer 3.1 Fixes many issues especially certain problems with difficulty changes and some of the freezing.

Ooooo there is a bug with diff changes? That might be why Avalon likes to freeze on some fast diff changing altcoins. Can you point to the commit where this is fixed? |

Just browsed over this funny fan review, I can barely hear what she is talking, and that "smoke test" really does not make any sense due to different lighting each time  https://www.youtube.com/watch?v=PdcQVOEq47E |

How to add "4th,5th pool" under "More Options" ?
Edit: Found it... add: "-o ip:port -O user:pass" for each pool
It even works with more than 5 pools...

Can different pools mine different coins, e.g., bitcoin and bytecoin? |
I try to be respectful and informed.

13:37 Guys don't forget to tip Xiangfu for his great work Good call. Tip sent. I've been using his build-avalon-image.sh script to build my own firmware images for WR703Ns with support for the various FPGA miners enabled. I've been using them to mine on Bitforce FPGA Singles, CM1s, and Ztex 1.15y boards. Unfortunately the Ztex bitstreams can't fit into the 4MB flash memory, so I've been loading them into RAM in /tmp after each reboot. I plan to try a usb-storage solution for that later. I can post my builds if anyone's interested. |

Sure, but I checked the donation part at the Avalon wiki and in my opinion Xiangfu did not really get enough "appreciation" for his work. |

Is this based off of commit 69bdc6f9883fbbf79e3e23d13cc6f2042154d072? needs to be running that or it's going to cause everyone problems. |

13:37 Guys don't forget to tip Xiangfu for his great work No tips for Aseras? Xiangfu clearly thanked him for the work. no one loves me... I leant my avalons to ckolivas for several days/weeks to do the firmware, paying him in hashes while he works. Luke never took up the offer, and the one try he bricked one of the avalons. ckolivas has never messed them up besides tripping a breaker once I also offered them to forrest to work on p2pool and he never took it up either. p2pool has serious problems with every asic right now. We have greatly improved the stability and hashrate. I have week+ uptimes now and rarely a hard lock anymore unless we hit the hardware reset buffer bug. We fixed a great many nasty bug including the difficulty bug, which prevented large shares such a solo mining from working. The watchdog would reset the avalon on high difficulty because it thought the unit was crashed. we found a lot of typos and debugged even building the firmware to make it a fairly simple process. We even taught ckolivas to get a VPN working under linux  I'd guess I've lost 50-100btc letting my avalons be used for development between downtime and "paying" whomever was developing. The next step is to chuck the usb-serial code and go direct usb and remove a lot of the hacks and work arounds that were used and improve it a lot more. ckolivas is greatly underpaid for the work he does. xiangfu is as well. He needs a new laptop. If avalon or anyone wants to thank or tip me, Id' rather they pester team avalon to get ckolivas an avalon in his hands. it will be worth it for everyone. It would also be nice if I were "special enough" to get my batch 2 avalons a wee bit quicker  |
