Hi, I set maximum no. of cpus as 2 in kernel and in RTAI. Module version was already disabled. The difference is that this time RTAI latency `./run` worked with 2 CPUs configured as opposed to previously when it failed so there is progress. However I still get 'Killed' when running `calibrate` Is there a BIOS option to disable hyperthreading? I have not seen this. [ 185.389229] I-pipe: head domain RTAI registered.
