If it has hyper-threading it has been turned off for the last 5 or 6 years, when Linuxcnc(emc2) was originally installed on it. Latency is fine with Lucid(RTAI). With Wheezy(RTAI) the latency test will not even open, it just hangs with nothing coming up in the terminal window, but the pc itself still keeps going (can open other programs). Are there any particular logs I should be looking at for pertinent error info? ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
