(In reply to Jianlin Shi from comment #8) > RCU stall messages still appear when run reproducer on 3.10.0-510. > Looks like I was missing a section of the patch which modified kernel/rcutree.c (the else clause). I've updated the patch and when my current -511 build finishes, I'll kick off a new build (also -511 based) which should fix this issue. I'll move to Modified when the build is done.

Server side script for testing the NAPI-POLL sfc issue
This script should run at x3650m2-01.farm.hsv.redhat.com (RT test box in the Huntsville lab).
From a console session run:
./SERVER
This test requires netperf2, already in the box. There is a note in the script showing how to get netperf2 code if necessary.

Client side script for testing the NAPI-poll sfc issue
This script mut run at rhelrt-17.farm.hsv.redhat.com (RT test box at the Huntsville lab).
From and ssh session run:
./CLIENT_17
Go to the console session and wait for the error.
Setting back to MODIFIED as there are patches in the tree to fix the originally reported issue, which I cannot reproduce in the current tree. The netdev stall is not RT-specific and not related to the previous issues in this BZ. If there are any other scenarios that lead to RCU stalls in the current tree, please file a new BZ with specific reproduction instructions. with steps in description, get error message on 327: [ 213.303023] INFO: rcu_preempt self-detected stall on CPU { 3}(t=60000 jiffies g=15011 c=15010 q=0) [ 213.303025] sending NMI to all CPUs: [ 213.303038] NMI backtrace for cpu 3 [ 213.303041] CPU: 3 PID: 9176 Comm: hackbench Not tainted 3.10.0-327.4.5.rt56.206.el7_2.x86_64 #1 [ 213.303042] Hardware name: Red Hat KVM, BIOS 0.5.1 01/01/2007 [ 213.303045] task: ffff8803fad52f00 ti: ffff8803fad1c000 task.ti: ffff8803fad1c000 [ 213.303054] RIP: 0010:[<ffffffff81041f8f>] [<ffffffff81041f8f>] flat_send_IPI_mask+0x8f/0xd0 [ 213.303055] RSP: 0000:ffff88041fd83d98 EFLAGS: 00010046 [ 213.303056] RAX: 0000000000000000 RBX: 0000000000000c00 RCX: 0000000000000000 [ 213.303057] RDX: 0000000000000c00 RSI: 0000000000000002 RDI: 0000000000000082 [ 213.303058] RBP: ffff88041fd83db8 R08: 0000000000022e08 R09: 0000000000000000 [ 213.303058] R10: ffffffff81d55de8 R11: 3a73555043206c6c R12: 000000000000000f [ 213.303059] R13: 0000000000000004 R14: ffff88041fd8fb80 R15: 0000000000000000 [ 213.303061] FS: 00007f6122f92740(0000) GS:ffff88041fd80000(0000) knlGS:0000000000000000 [ 213.303062] CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b [ 213.303063] CR2: 00007fff9dbb6fa0 CR3: 00000003f996a000 CR4: 00000000000006e0 [ 213.303068] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 213.303073] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 [ 213.303073] Stack: [ 213.303076] 0000000000000082 0000000200000004 0000000000000001 0000000000000003 [ 213.303078] ffff88041fd83de0 ffffffff8103c7c1 ffffffff81974e80 0000000000000003 [ 213.303079] ffffffff81974e80 ffff88041fd83e40 ffffffff811170f9 0000000000000082 [ 213.303079] Call Trace: [ 213.303083] <IRQ> [ 213.303088] [<ffffffff8103c7c1>] arch_trigger_all_cpu_backtrace+0x181/0x190 [ 213.303092] [<ffffffff811170f9>] rcu_check_callbacks+0x399/0x770 [ 213.303097] [<ffffffff81081f22>] update_process_times+0x42/0x60 [ 213.303101] [<ffffffff810cdbb5>] tick_sched_handle.isra.19+0x25/0x60 [ 213.303103] [<ffffffff810cdd94>] tick_sched_timer+0x44/0x70 [ 213.303107] [<ffffffff8109e175>] __run_hrtimer+0x85/0x270 [ 213.303109] [<ffffffff810cdd50>] ?
