Thanks kano, --no-restart worked, you are right, the fan reading on gpu 3 fails, even though
all three cards are 5970s, so there is actually just 1 fan on each card..

Strange that it works with card 0 and card 2, but not card 1 ?!

Maybe a BIOS error of the card ??

I actually only have the problem on this particular rig..

here a screenshot:

My only guess now, as I mentioned before, you may need --gpu-map
It looks like it not associating the fan with both GPUs ... but I don't have any dual GPU cards so I've no idea other than read the README

I've had few H/W error before also, but cgminer 2.7.6 seems to "freak out" and crashes randomly when a h/w error occurs.

thats not the case with good old 2.4.2, it just counts up the errors

As per the README FAQ ...
Add "-T -D --verbose"
and post a log

However, it's better with a core dump to show exactly where the problem is.
Before you run cgminer:
ulimit -c 2097152

However that won't give much details about where it crashed without:

If you compile it your self, then (as I said 2 pages back):
CFLAGS="-g -W -Wall" ./autogen.sh --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt
make clean
make

And of course you don't have to include all the options on the end you don't need ...

Once it crashes you'll have a core.nnnn in the directory
where nnnn is the process number.
Find it with
ls -ort core*

Then:
gdb cgminer core.nnnn
bt

and bt will tell you where it crashed ... to add to the pastebin

~~Edit: however, with that many errors, it's likely to just be in the ATI driver and you probably need to clock it down more?~~
Nope - it doesn't look like it's lots of error in the HW: counter ... anyway as above ...

After upgrading some of my rigs most of them fail with this segmentation fault:

Weird, I've been getting HW errors after upgrading to 2.7.6 also. I thought my GPU was on the way out because I've never gotten any before.

While I see r-pi listed in the subject, I see no instructions or downloads provided. Am I missing something?

stock 700mhz ARM gets right around 118Kh/s.

You do not mine with the hardware itself... you use it to attach FPGAs to mine with.

I think it was more of a statement, "cgminer works on a Pi" like "cgminer works on Windows". I personally have many BFLs on several Pi, for which it works rather well. Actually mining with it, not so much.

i got my 2nd pi in the mailbox last week. at the moment i got some problems with wireless under raspbian. want to drive my ztex single and ztex quad with it anytime soon... :-D

well... if someone would reverse engineer the videocore there might be a possibility to write a shader for sha256 mining on the raspberry pi. but without broadcom opening the videocore that wont happen...

EDIT: on my 1100MHz arm seagate dockstar its about 200Kh/s

For Raspbian, my steps went something like this:

install required parts:

Quote

sudo bash
apt-get install build-essential git dh-autoreconf libcurl4-gnutls-dev libusb-1.0-0-dev libusb-dev libncurses-dev libudev-dev yasm screen

grab latest version:

Quote

cd /usr/src
git clone https://github.com/ckolivas/cgminer.git
cd cgminer

tell it to configure itself

Quote

bash ./autogen.sh --enable-scrypt --enable-bitforce --enable-icarus --enable-modminer --enable-ztex --with-libudev

upon successful configure with no errors, compile it

Quote

make all

upon successful compile, run in "benchmark" mode to make sure it's alive

Quote

./cgminer --benchmark

stock 700mhz ARM gets right around 118Kh/s.

[edit: added libudev-dev - thx for pointing out the miss]

I tried to update an old rig from 2.4.2 to 2.7.6 but 2.7.6 just hangs after the pool messages and does nothing..

I can abort with CTRL-C.. The old 2.4.2 runs fine though ?!

Here is a log:

http://pastebin.com/ACe6QDi9

I can see no problems there either, but cgminer is not "switching" into the "normal" view with the cards, it just sits at the pool "overview", saying that the pool is alive and does nothing else..

Up to the point below it looks fine ... has found and accepted shares ... but then:

Code:

[2012-09-27 13:57:38] Attempting to restart cgminer 2.7.6

In the current code that's only called by
1) You press S C Y
2) You send a restart to the API
3) Getting GPU fan speed fails

Thus it must be 3) (1 and 2 aren't possible in that log) and somehow it can't access your fan info for one of your GPUs

Maybe --gpu-map is required to fix it?

Using --no-restart will show that is the cause of the problem - but not fix the actual problem.

The only thing about the loop is don't restart cgminer from in cgminer settings restart. It will stop cgminer then cgminer itself restarts it and the loop keeps trying to start cgminer giving you no devices restarting message in the middle of cgminer working messages. Aside from that it works and is about what I do.

This will not set realtime but will show how to set a delay.
No need for cash. Was super easy to setup. You can set any options you like mine are there yours likely wont have --disable-gpu.

Code:

:Loop
cgminer.exe --disable-gpu --api-allow 127.0.0.1 --api-listen
ping -n 15 127.0.0.1 > NUL 2>&1
GOTO Loop

ping -n 15 blah blah blah the 15 is the time in seconds for the delay. Seems accurate enough. It pings home every second.

Or with a little more added

Code:

@echo off
:Loop
REM cgminer
Set NOW=%date:~10,4%%date:~7,2%%date:~4,2%.%time:~0,2%%time:~3,2%%time:~6,2%
cgminer -G --api-listen --api-allow W:127.0.0.1,R:192.168.0.0/24 --api-description Windoze 2> "run.%NOW%.log"
echo Sleeping for 5 seconds
ping -n 5 127.0.0.1 > NUL
GOTO Loop

So you get a log of each run also like my linux script
(of course set 192.168.0.0 to match you network - and also set it to W: instead of R: if you want to allow cgminer control from other computers on the same network)

Found a small bug. If send a request gpurestart|0 by API, cgminer very much starts to load the CPU ~ 100%.

GPU restart isn't always going to work in all situations.

Unless there is a code bug and you've found an infinite loop - it's most likely a driver issues and if you find with your driver version+card it's problematic - don't use it.

Waiting for Stratum support too.

Regarding stratum, I have been working on it. It is very much a non-trivial task to do in c so it's taking a while and I'm progressing very slowly and cautiously. Furthermore, the work generation is totally orthogonal to the current cgminer network scheduler I spent so much time creating, so it needs to rip great big holes into the current code to circumvent it. There's a stratum branch in my git tree if people want a peek but it's just code in progress and unusable.

Sent a donation. Just started using CGMiner. Waiting for Stratum support too.

I will have my new static IP in a couple days. Will have ftp up if you would like me to host your miner files. I am on a 100/25 connection. Should be good enough. Let me know if I can help in any other way.

Much appreciate the donation

My own server is not a problem, it's me sending heaps of uploads there that is the rate limiting step and no matter where I send them the same issue occurs. Thanks though.

Is there a way to make mining on a PC that has a AMD 7950 and Intel HD Graphics possible?

My Motherboard is a Z68, I would like to connect 1 or 2 Computer Displays to the HDMI and DVI on Z68 motherboard and 1 or 2 displays to my AMD 7950.

When I start Cgminer it says too many gpus or something along those lines.

Yes there is, but you will need to use a combination of parameters to these options: -d, --remove-disabled, --gpu-platform and --gpu-map. Start with 'cgminer -n' to read what cgminer finds and then read the advanced section on gpu-map in the readme.
