Hello, I installed RTAI 3.4 and comedi-0.7.73 and also the CVS snapshot on a system running Suse 10.1. When I trie to load the comedi modul I get a segmentation fault.. Here is the dmesg output I-pipe: Domain RTAI registered. RTAI[hal]: <3.4> mounted over IPIPE-NOTHREADS 1.3-00. RTAI[hal]: compiled with gcc version 4.1.0 (SUSE Linux).
