Can you post the cgminer.conf file you are using? Does it have the --text-only option? Or do you start with this option? The option -t is the same? Do you use this one?
I'm not using conf file and neither --text-only
Only executing command:
sudo ./cgminer -o stratum+tcp://pool.ckpool.org:3333 -u btcaddress -p xxx --suggest-diff 32 --gekko-2pac-freq 225
Thanks
