Hello Experts, I'm using mostly default configuration, Linux-3.16, RTAI-4.1. Initially I was having issue with "timer does not work through interrupt remapped IO-APIC", I solved that issue by disabling VT-d option in BIOS after much googling. I also disabled hyper threading in the BIOS. I believe a few things in my config files need modification, I don't know what are those. If someone properly guide then I'd be happy. Please let me know if you need other info. Thanks, Hasan _______________________________________________ Rtai mailing list [email protected] https://mail.rtai.org/cgi-bin/mailman/listinfo/rtai
