Steven, Could you please include the patch that Thomas suggested for the timerfd hangs in the email thread (link below), if Thomas is fine with the patch? I did verify that that patch fixed the hangs that I saw on a panda board (ARM Cortex A9 dual core). http://marc.info/?l=linux-rt-users&m=132753755612168&w=2 Thanks, Sankara -- 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
