Hmm, no segfaults anymore, but still not all chips there. Also it seems that i need to start and stop chainminer before running cgminer to get it finding even those few chips. And those few chips produce only invalid nonces it seems.
Pastebin of the output:
http://pastebin.com/Cp7jSjeJThe code i built is from github and i haven't modified it. BITFURY_MUX_OE is not defined. No parameters in commandline, except url and --no-submit-stale
edit: oh and running BFGMner for and hour or so resulted total speeds 170/160/149 or so. The last number was quite well in line with ghash.io's speed.
With anjavi's cgminer it is possible to set speeds per chip. But even with the same clockbits as in best.cnf, the speed is something like 20 - 30 ghs lower than chainminer.
