cgminer hangs when mining litecoin through gpu

[POMATu]

Hi,

I am trying to run cgminer on linux machine. I have already tried different versions of reaper, and it don't work (just cant connect to pool). Now I am trying to use cgminer. Everything is ok with mining bitcoins via gpu and also mining litecoins via cpu.
But when I try mining litecoins through gpu it just hang on the message

Code:

[2013-01-12 01:30:47] Started cgminer 2.10.4

I am having nvidia 8500
arch linux x86_64
using notroll.in pool

When I am disabling ncurses with -T option, I am seeing this

Code:

 [2013-01-12 01:34:48] Started cgminer 2.10.4

 [2013-01-12 01:34:50] Switching pool 0 http://notroll.in:6332 to stratum+tcp://notroll.in:3333                    

and silence again... Only stratum notifies me about new blocks

here is an verbose output

How can I make it work?
Thanks

Everything is working now. Seems like I should wait for 10 minutes after start, then it starts working.

btw where I can find shaders count table? I need to specify shaders count on my nvidia 8500 gt

[debianlinux]

A) Provide your command line arguments for threads like this

B) Glad it is working, sometimes it can take a minute or so for the thing to get rolling. 10 minutes is excessive but if you have a high intensity it is possible the screen isn't refreshing until well after launch (if you are driving your display with the same GPU you are hashing on).

C) According to this you get a whopping 16 shaders on a 8500GT (I cannot verify).

Hello,

I have probably a very similar problem. My cgminer does not move forward from the phase of kernel compilation. The same problem actually occurs with reaper miner as well. There is no point in waiting, as I waited usually about one hour or more and it did not help.
I use gentoo linux distribution. I have never managed to run cgminer without faults, when I try to mine bitcoin it crashes. Therefore, for bitcoin I use rather phoenix miner (and stratum proxy), it works very well.
My card is Radeon HD 5850. I use ati-drivers/catalyst 12.8. I have jansson-2.3.1 installed.
I compiled cgminer from sources using following configuration:
CFLAGS="-O2 -Wall -march=native" ./configure --enable-scrypt --without-libudev --without-curses
nevertheless it did not work even when --enable-scrypt was the only option.

cgminer output:

Code:

~/scripts $ ./cgminer-2.11.3/cgminer --scrypt -o stratum+tcp://notroll.in:3333 -u USER -p PASS --thread-concurrency 5600 -I 18 -g 1 -w 256 -d 0 --verbose -D

Given that there is a problem with both cgminer and reaper and this problem occurs at the same moment, my hypothesis is that it is rather a system issue than a miner issue.
Any ideas? Thanks.

EDIT: Solved by upgrading AMD-APP-SDK and ati-drivers to the latest version.
