hi fireduck,
I'm getting more and more of:
Pool 0 not providing work fast enough
when mining here, is there something you can do to improve this?
thanks.

ps. I have a little more than 7 GH/s

TML version 1.11 has been posted. This includes a new bitstream "leibniz" with support for two additional boards, the "x2" and "dominator". You should stick to "kreisel" unless you have one of these boards; it is faster and is still the default. Dominator users, add these arguments when invoking the TML:
-Dbitstream=leibniz -Dclock_pin=csg484.W11 -Dclock_pin_freq=6.666
X2 users, add these arguments when invoking the TML:
-Dbitstream=leibniz -Dclock_pin=fgg484.H22
Hi Eldentyrell, any news about cairnsmore boards? Thanks. spiccioli |

Must of missed that (or don't remember), I've just find it odd, what could of caused it to just start happening.
At least I know why now, I don't even know for sure if a new powered hub will help.
Lethos, I don't think a powered hub can help you here since it is an OS/driver problem as far as I know. spiccioli |

However the reason for the entire system slowly crashing, while still kind of working, was the usb stick was becoming undetectable, either by becoming unmounted or ejected, as soon as any of the CM1's was connected via usb. I use a wireless mouse (usb bluetooth) and usb thumb drive since the beginning, it has always been that way, but this most recent problem only effect the thumb drive. I even tested if it temporarily effected the mouse and it did not.
Hi Lethos, this is a problem which surfaced in the past, see old thread messages, where attaching a usb device sometimes makes a different one to disappear. If I'm not wrong this problem was on windows back then. Anyway, good to know it happens on linux as well. spiccioli |

Since no one gave any suggestions, just thought I'd let you know I'm going to try moving everything over to a Debian configuration.
To the best of my knowledge, it should work without any issues to run Cgminer and XBMC it's two main purposes on there.
Ubuntu, may have been the popular choice, but going back to a more stable and reliable OS, rather than user friendly one, will hopefully help.
Lethos, I'm using ubuntu _server_ 12.04, and I'm not sure I do understand you correctly, but if you're running it from an USB stick I'd try to run it from an old HD or a SSD (small ones are cheap these days). I'd also try not to use it as an HTPC at the same time. If you try, install just the base server, and the ia32 libs. No X server, no fancy desktop and so on. Problems = parts^2.  spiccioli |

Hi LazyOtto, no need to search anymore! 16CtsQsV6bPrtzc3DaYvDHjsHS5MwXL476  spiccioli <lol> Thanks, spiccioli. I'm starting my bitcoind / wallet now to send a trivial amount of BTC in appreciation of your quite non-trivial amount of help. ty BTW, my personal amount sent is trivial. I'm hoping though that the idea is *lots* of people send small amounts and they add up. Thanks a lot LazyOtto, it is very appreciated since every Satoshi counts! spiccioli. |

-- edit -- Edit, assuming I can find your address. (I routinely run with signatures disabled. Cuts out a lot of 'noise'. But I'll re-enable and search for your's.) Hi LazyOtto, no need to search anymore! 16CtsQsV6bPrtzc3DaYvDHjsHS5MwXL476 spiccioli |

Actually ~ 80% of the hashing power is directed to abcpool, the 20% remaining is split between p2pool, ozcoin and btcguild.
Regarding solo mining I am planning to do it, but I am not convinced to point miners directly to bitcoind. There are almost no info about the progress and it would be harder to check if something is going wrong. I'm planning to install a backend (like pushpoold) and use it for mining. I am doing some tests in these days, when it will be ready I will announce it here. Any advice is welcome.
If I were you I'd point all to p2pool with a high difficulty, like 1000 or even more, so that other lower hashing power p2pool miners are not too affected. spiccioli ps. You could also try to use http://hhtt.1209k.com/ which is PPS with a low fee when using high difficulty shares. |

[very useful stuff]
spiccioli, the post I quoted was tremendously helpful, thank you. (IMO, that info should end up on whatever 'tips and tricks' documentation Enterpoint eventually puts together.) A question however, while following the steps you suggested the USB ports get correctly recognized, enabled and mapped but are not accessible until I do a "sudo chmod a+rw /dev/ttyUSB*". Do you have a suggestion so that, from a USB unplug/plug, the ports are usable without that manual step? FYI, I'm running the Debian 7 beta release as the OS. (Seems the Debian 6 stable wasn't quite good enough. Needed a newer revision kernel to get the USB stuff to behave.) And, shouldn't be relevant, but 'just for kicks' I'm doing it on a PowerPC G4 bit of hardware. LazyOtto, to access them I had to add the group ubuntu adds to every ttyUSB device to the list of secondary groups of the user running cgminer $ ls -l /dev/ttyUSB*
...
crw-rw---- 1 root dialout 188, 9 Sep 8 01:04 /dev/ttyUSB9
...
So I issued a sudo usermod -G dialout my_login_name
to add user my_login_name to the dialout group. This made all /dev/ttyUSB* devices fully accessible to the user running cgminer. spiccioli. |

spiccioli,
udev works charming:) you made my day thank you
loshia, you're welcome. spiccioli |

Guys,
I am tiring to map my lancelets to particular names in order to be able to know which cgminer ICAxx corresponds to which board. I am using xubuntu 12.04.
I have tried following (udev rules):
ATTR{idVendor}=="0403",ATTR{idProduct}=="6001",ATTR{serial}=="A101LSVA",SYMLINK="ttyLancelot2"
When I tested it the serial A101LSVA corresponded to /dev/ttyUSB2 with board attached and working
However /dev/ttyLancelot2 always was symlinked to /dev/bus/usb/003/026 or something and cgminer refused to work. When I manually symlinked /dev/ttyLancelot2 to /dev/ttyUSB2 all was fine. How to make udev to symlink to /dev/ttyUSBxx instead of /dev/bus/usb/xxx/xxx
10X
loscia, I did it like this for my CM1 boards: https://bitcointalk.org/index.php?topic=78239.msg1091298;topicseen#msg1091298spiccioli. |

I also have random users form time to time.
IMO setup is easy to do so any1 can run own node and use public ones just as backup.
same here, sometimes someone mines an hour or two or even less. spiccioli |

Ok thanks, I'll wait until it uses a stable bitcoind instead of a test one. spiccioli |
