There is a proposed fix by Paul Gortmaker from October 2014 that I replied to here: http://permalink.gmane.org/gmane.linux.rt.user/12699 We will try to reproduce the problem quicker using your suggestion (2 iperf clients). Keep us posted if you get a reply from someone with more RT and mutex experience. -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
