So it looks like one of the fans of a pod is giving up the ghost on me.  It was one I had pre-ordered way back when.  I figured I'd ask, where might be the best place to source a replacement fan?  They're what, something like 4.5 CM square?

Ok, new issue.  cgminer crashed out with this error report.

Failed to create restart thread errno=12 in cgminer.c restart_threads():5063

One of my pods appears to restart a great deal, even at stock speeds.  It was up to being the 229th device in cgminer.  The rest were still 0 through 6.

I've been hearing this creep up more on the Pi.

For now set this option on if you spot kernel messages floating around:
https://bitcointalk.org/index.php?topic=494625.msg5932931#msg5932931

Every case mentioned so far has been solved by that.

Meanwhile, I'll see if I can recreate and trace it.

Thanks vh.  So far that appears to have fixed it.

Well, a week later, and my efforts to engage with BTC support staff have gone from fruitless to infuriating.  They just keep telling me that my current BTC balance isn't enough to be paid out.  I keep saying I know that, it's the previous balance which claims it was already paid out to a specific address at a specific time, and wasn't, that I'm emailing about.  They just go back to my current balance not being enough.

If anyone needs a reason to stay away, there you go.

So, I got my 2 pods a while ago, and they were running fun until just recently.  Now they don't seem to run for more than 12 hours.  It appears Rasbian itself is crapping out.  I left an ssh session logged in while I was at work today to attempt to catch what happens, and this is what I saw when I came home.

I've checked to make sure I have the latest drivers, and everything claims it's up to date.  I'm going to try to narrow this down by going back down to stock clock, although I'm only at 175 right now, so it's not that far above stock.  Also going to try one pod at a time.  Anybody else seen anything like this?

Got mine!  Have them up and running on the same Pi 3B board as 5 2Pacs.  I backed everything down to stock for now to see if the USB bus gets congested, but so far so good.  The 2pacs are all humming along at ~11Gh/s (plugged into a 7-Port Superpbag USB hub), and the pair of pods I got are churning out their ~66Gh/s (plugged directly into the Pi 3B).  One of them is churning out more HW errors than all the others.  Up to 8 of them in about an hour or so, which isn't outrageous.  That aside, so far so good!

no, for me it's ok. Payout to an exchange so it takes few more hours to appear but no problem for now.

Yeah, I have it payout to an exchange as well.  It's not that it's delayed.  It's that it's flat out not in the transaction they say it is.  Look for that address in that transaction, it's just not there!

I tried emailing support@btc.com, and all I got back is to check with my wallet provider.  I tried clearly explaining the issue again, and so far nothing.  Pretty sure I'm just shit out of luck.  Time to switch pools.

Has anyone else had BTC pool claim they've made a payment to you, but just not?  My earning dashboard is claiming about 0.001 BTC was paid to 17KJisKa8xsK5cTbYP99K6oLr87nkWvHbw in transaction 4115ebea8f56049af468543716d8d0f218b6a3181442591460e5a31b2fbfcd21, but there is zero sign of that actually being included in that transaction.  Been mining there for about a year and this is the first time anything like that has happened.

Question for anybody who knows.

I know this is a essentially a one man operation.  So should I expect any sort of notice when my 2PACs ship, or will they just appear in my mailbox one day?

You gotta consider a 2Pac at 150MHz is going to be pulling about 1.4 amps. That's not insignificant.

so drop the freq and/or get a more powerful hub?  suggestions on hub?

FYI,  I feel like an idiot for not realizing that it had to do with power per port.

I almost bought the 10 port Sipolar hub a few posts up that only provide 0.6 A per port.  Luckily I was able to cancel my order.  I must have been looking at hub specs so long I'd gotten confused about which hubs had which specs when I ordered it.  Maybe I got it confused with a different Sipolar 10 port model that did provide 2A per port.  No idea.

I'm currently running a pair of 2PACs on a Superbpag 7 port hub which is rated at 2A per port.  I have them up to 225Mhz which is as much as I dare with my current cooling solution.  Going by the spreadsheet on post 1 of the support thread, that should have them pulling something like 1.75A, especially since I have the vcore tuned as close I could without hardware errors.  But I suppose it could be a bit above that.  The heatsinks are warm enough to be uncomfortable to the touch, but not immediately yank my fingers away.  So I think I'm ok.

I'm hoping to get a few more 2PACs and then we'll see how well the hub holds up.  I think I read elsewhere that running this hub at 100% capacity with poor ventilation for extended periods killed it pretty hard though.  So we'll see how things progress.

Long time reader, first time poster here.
I just  wanted to say thank you to everybody for all the amazing information that I find here. Right now I am running CGMINER VERSION 4.10.0 on a Raspberry Pi3. I have four Gekko 2Pacs running perfectly with their frequency set at 250. My average hash rate is 112 Gh/s. I have my 2pacs running through a Superpbag USB hub, and have had no issues since making sure the sticks were getting the right amount of power. A lot of trial and error, other USB hubs, USB y connectors etc. But the Superbpag has had a perfect run with the four sticks. I have multiple fans cooling them with some extra added heat sinks.

I got the 2pacs and had minimal experience with Linux. The help here made it easy to get it up and running and the guys running the show are very skilled and knowledgeable.  The students in my classroom have become awesome at researching and learning from all of you. Their confidence has been building and they have no fear of working with hardware and software. I truly appreciate all the help and guidance here. Very informative and professional!

Sometimes we do have little issues here and there, but all seem to be easily resolved with the support and help here.

Sorry for the random post. I just was doing my daily read of the forum and wanted to chime in and say thanks to all!

I think you have a near identical setup to myself, but you're clearly a bit further along this rabbit hole than myself.  I'm running two 2Pacs through the Superpbag 7 Port USB hub.  I currently have them at 225 and I think that's about where I'll leave them.  I may even dial them back a bit.  I'm trying to figure out if they are running too hot at 225 with the fan I have on them.

Out of curiosity, where did you put the extra heatsinks?

So, possibly stupid question, but I'm new to this.

I'm currently running a pair of 2PACs at 150MHz with Raspberry Pi controlling them.  I can tell ample power is a constant issue.  I have one clearly substandard USB hub that is powered, but only has a 2 amp power supply.  If I try to run both 2PACs on it, eventually one drops out.  I can however run 1 off the Pi unit itself, and one off the hub.  But that is less than ideal, especially since I'd like to clock them higher.

I have another powered USB hub that is not compatible with Raspberry Pi, but which has a 3 amp power supply.  On a scale from "Go for it" to "You're gonna fry you 2PACs", how bad of an idea is it to just use the 3 amp power supply with the hub that normally uses a 2 amp power supply?

Alternately, I did order a Sipolar 10 port HUB, so I could just wait for that to eventually show up from China, but I've caught the bug a bit...
I think there are a lot of unknowns with your question. It is hard to make a judgement call regarding your hub and 3A power supply. One of my concerns would be does your hub and power supply both use barrel connectors or micro/mini USB? If it uses a barrel connector, you need to ensure that your polarities match between the two and that they are the same size.

They both use barrel connectors, and the polarities are the same.  I was slightly mistaken about two things however.  One is 5V, 2A, and the other was 5V, 5A.  Regrettably, I was also wrong about connector compatibility.  One is just ever so slightly larger than the other. 

I attempted to daisy chain them as well, and still no luck.  The Pi doesn't recognize anything at all plugged into it.

I'll just have to wait for my sipolar 10 port to get here.  It's encouraging to see other people have had good experiences with it.
