Testing this with what is largely a x86-64 defconfig but with RT_FULL, I now see: root@dell760-paul:~# dmesg|grep NOH [ 8.605854] NOHZ: local_softirq_pending 100 [ 8.732677] NOHZ: local_softirq_pending 100 [ 8.852729] NOHZ: local_softirq_pending 100 [ 8.963964] NOHZ: local_softirq_pending 100 [ 9.061892] NOHZ: local_softirq_pending 100 [ 9.184921] NOHZ: local_softirq_pending 100 [ 9.370958] NOHZ: local_softirq_pending 100 [ 9.657811] NOHZ: local_softirq_pending 100 [ 9.942631] NOHZ: local_softirq_pending 100 [ 10.783710] NOHZ: local_softirq_pending 100 root@dell760-paul:~# ...early in boot (we cap them after ~10 msgs). I think 100 is RCU if I did my bit counting properly; remind me to submit a patch that uses the human readable names. I had a good hunch which commit was responsible but I did a check of it and the one directly underneath it to be sure, and the latter boots w/o any pending messages. git log --oneline v3.14-rt ^v3.14.64 [...] 0a80a6849f19 latencyhist: disable jump-labels a884ef48e1ca net: provide a way to delegate processing a softirq to ksoftirqd 780d7ca2fdb0 softirq: split timer softirqs out of ksoftirqd <------ *** fail *** 13ad3a61e2c2 preempt-lazy: Add the lazy-preemption check to preempt_schedule() d0bb90f40dbf net: move xmit_recursion to per-task variable on -RT 88f1b110f64d ptrace: don't open IRQs in ptrace_freeze_traced() too early 816f701e4c91 Linux 3.14.61-rt63 Have not investigated further yet; going to go test 3.10-rt since in theory it should have the same issue; it has the same commit. If it does, I'll follow up the announce for it with similar details.
