ok I burned the image to a new microsd and got the same result then when I tried to upgrade (Reinstall) the latest firmware from their support site (I tried the tar and the .sd) - I got this error:
(initramfs.bin.SD-20140410.tar)
System Upgrade Failed
mount: mounting /dev/mmcblk0p1 on /tmp/847.boot failed: No such file or directory umount: can't umount /tmp/847.boot: Invalid argument
I have the same problemwith one S2 now. Has this been fixed anywhere? I have the problem now with 3 S2...

Where is the micro SD card located in the S2? Mine keeps resetting to factory settings after every reboot, so I am going to try a new SD card.

on the BB-middle board: you have to remove #6 or both #6 and #7 board(s) to gain better access; it is very tiny-push it "in" and it pops out.

Flashed a new SD card and that seems to have done the trick. Now the only issue is all the fan speeds report as 0 even though they are running fine, and sometimes the temperature of the cards report as 0 as well. But at least everything is working properly now.

Yeah don't worry about that, its not symptomatic of anything worse.

Got my first S2 yesterday. Mining happily away. I noticed that the #9 chain is not showing the temperature. Could that simply be a loose connection? I wasn't trying to power down to take it apart. Or should I be concerned?

I'd ignore it, not seen a solution yet. Might be dead sensor in the actual board, lose internal connector, bad external connection, we just don't know. Makes no difference though.

Hi guys My S2 has been working fine now for a couple of weeks on BTCguild pool but since yesterday it's slowed down on average from 1000 to about 950.
Checking it out via the control web page there seems to be nothing wrong at all everything is normal temps are all below 55.
Any idea what the cause might be? Could it be the pool? The speed is showing as slower than normal on the miners web page too, I can't see the LCD it's remote.

I have had a S2 for a couple of weeks now and one of the boards is doing the same, and as said it hasn't caused any problems. Wouldn't sweat it.

Some people said that they have it working better on eligius. I, personally, had above 99% luck with S2 on eligius.

Hey guys, I am having some trouble with a miner I just received, just sent an email to Bitmain, but any support would be appreciated. Here is the problem...
I received my S2 unit today. I opened it and immediately plugged it in and ran into a few problems that I am unsure of the cause of. When turned on, the LCD lights up, but nothing shows up on it. When I go to IP 192.168.1.99, it shows the main screen, but does not asks for login information, and whenever I try to click on any of the other tabs, it tells me that the webpage is unavailable.
After turning it on and off a few times, I opened up the case and removed all but one of the hash boards and made sure that everything was plugged in correctly, including the SD card. Still received the same problem. Then I switched the board that was in slot 1 with another hash board, and then tried to turn it on again. I was able to login and set my pool information, but when I looked at the miner status page, it showed that all the work was discarded and nothing was showing up on my pool. I rebooted it a few times, and every time it was rebooted, the pool information was reset to factory settings. I also noticed that the hardware version was not displaying anything like it had for my other units. After another reboot, I was back to not being able to login, and instead getting the main page, and not being able to click anywhere. I tried most of the different hashboards in slot 1 and every single one was giving me the same problem.
If anyone has any ideas please let me know, thanks for the ideas...

Reimage the SD card, if that still doesn't work replace the SD card entirely.

I posted earlier and said my miner seemed to be slowing down but everything looked normal, well it did until I changed pools on it then the number 1 chain seemed to have errors mostly a line of dashes with 3 or four 0's on the end. This morning when I looked there are now a couple of x's in there too.
Any ideas? The card with the errors is running cooler so I guess that's the one that isn't working.

Try reseating it, and or swapping a card in that slot.

My S2 does this frequently, and I've found that I have to shut the unit down (via SSH), kill the power, allow the PSU to reset, fire it back up, let it run for 10 minutes then restart cgminer (via the miner configuration page, just re-applying settings) to get it to run "smoothly" after I lose a line of ASICs. I still secretly blame the PSU for this, but I don't have an EE degree to back that up with! Overall this device is not as trouble free as it's little brother, and I hope BITMAIN plans on a more stable upgrade path with their new chips.

I've tried swapping cards, and can't identify an issue with a specific card, to clarify.
