Hi,
I am trying to mine on a machine with 2 r9 290 cards. I run cgminer and it starts without any errors, but after a few seconds of work my computer crashes and I have to restart it using the power button on the back.
I tried ubuntu 12.04 server 64 bit with xdm, then installed xubuntu on the server and also tried running batm from a usb stick. Same results.
I am using catalyst 13.12 linux drivers.
I am currently running the pre-built cgminer 3.7.2. I also tried building it from source but it segfaulted when I tried to start it.
I also installed app sdk 2.9 and adl sdk 6.0 when I tried to build cgminer.
I tried these cgminer configurations:
1. --scrypt -o stratum+tcp://gigahash.wemineltc.com:3333 -u .1 -p -g 1 -w 512 --lookup-gap 2 --thread-concurrency 24500 -I 20 --gpu-fan 70 --gpu-engine 947 --gpu-memclock 1250 --gpu-powertune 20
2.

I also tried with a 947 clock instead of 1000. same results.
This is my hardware configuration:
