Public bug reported: I can consistently reproduce this with the Ubuntu 17.10 kernel. It never happens with a mainline 4.13.11 kernel built from source.
To reproduce: 1. clone https://github.com/nodejs/node (currently at commit 4ca4db0d4c) 2. ./configure && make -j8 3. ./out/Release/cctest cctest is sometimes killed, sometimes locks up the computer. When the computer is still usable, the following message is logged: [36488.886799] BUG: unable to handle kernel paging request at ffffdf3cd60001a0 [36488.886824] IP: kfree+0x53/0x190 [36488.886831] PGD 0 [36488.886831] P4D 0 [36488.886844] Oops: 0000 [#2] PREEMPT SMP [36488.886851] Modules linked in: xt_tcpudp iptable_filter cfg80211 binfmt_misc snd_hda_codec_hdmi intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel pcbc aesni_intel aes_x86_64 crypto_simd glue_helper cryptd snd_hda_codec_realtek snd_hda_codec_generic intel_cstate r8712u(C) intel_rapl_perf snd_seq_midi snd_seq_midi_event input_leds snd_hda_intel snd_rawmidi snd_hda_codec snd_hda_core snd_seq snd_hwdep snd_pcm snd_seq_device snd_timer snd ie31200_edac soundcore mei_me shpchp mei lpc_ich mac_hid cuse parport_pc ppdev lp parport ip_tables x_tables autofs4 nouveau mxm_wmi wmi i2c_algo_bit ttm drm_kms_helper syscopyarea sysfillrect hid_generic sysimgblt uas ahci fb_sys_fops usbhid usb_storage r8169 drm libahci hid mii video [36488.886940] CPU: 6 PID: 21882 Comm: cctest Tainted: G D C 4.13.0-17-lowlatency #20-Ubuntu [36488.886947] Hardware name: MEDION H77H2-EM/H77H2-EM, BIOS EM0411-M8 04/11/2012 [36488.886951] task: ffff8ebd7c18a640 task.stack: ffffa003ce10c000 [36488.886957] RIP: 0010:kfree+0x53/0x190 [36488.886961] RSP: 0018:ffffa003ce10fd30 EFLAGS: 00010282 [36488.886965] RAX: 0000000000000000 RBX: 0000000000006fa8 RCX: 0000000000000002 [36488.886970] RDX: 0000314521002bc0 RSI: 0000000000010080 RDI: 0000714500000000 [36488.888247] RBP: ffffa003ce10fd48 R08: 000000000001f640 R09: ffffffffa27c7979 [36488.890131] R10: ffffdf3cd6000180 R11: 0000000001000000 R12: ffff8ebe84406900 [36488.892024] R13: ffffffffa23aa5ee R14: 0000000000000000 R15: ffff8ebe8c611820 [36488.901718] FS: 00007f7666764b80(0000) GS:ffff8ebe9ed80000(0000) knlGS:0000000000000000 [36488.906872] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [36488.908816] CR2: ffffdf3cd60001a0 CR3: 00000002fc3c5000 CR4: 00000000001406e0 [36488.910711] Call Trace: [36488.912512] security_sk_free+0x3e/0x50 [36488.914232] __sk_destruct+0x108/0x190 [36488.915872] sk_destruct+0x20/0x30 [36488.917483] __sk_free+0x82/0xa0 [36488.919064] sk_free+0x19/0x20 [36488.920626] tcp_close+0x230/0x3f0 [36488.922183] inet_release+0x3c/0x60 [36488.923714] inet6_release+0x30/0x40 [36488.925242] sock_release+0x1f/0x80 [36488.926785] sock_close+0x12/0x20 [36488.932837] __fput+0xe1/0x220 [36488.937778] ____fput+0xe/0x10 [36488.942441] task_work_run+0x76/0x90 [36488.943956] exit_to_usermode_loop+0xc4/0xd0 [36488.945467] syscall_return_slowpath+0x59/0x60 [36488.946973] entry_SYSCALL_64_fastpath+0xa7/0xa9 [36488.948468] RIP: 0033:0x7f7666376df0 [36488.949967] RSP: 002b:00007ffe98391250 EFLAGS: 00000293 ORIG_RAX: 0000000000000003 [36488.951522] RAX: 0000000000000000 RBX: 000000000000000c RCX: 00007f7666376df0 [36488.953073] RDX: 0000000000000000 RSI: 0000000000000002 RDI: 000000000000000c [36488.954639] RBP: 000000000000000c R08: 000055a301618920 R09: 000000000000000a [36488.956208] R10: 00007ffe9839126c R11: 0000000000000293 R12: 0000000000000011 [36488.957774] R13: 0000000000000020 R14: 0000000000000001 R15: 00007ffe983916ec [36488.959354] Code: 00 80 49 01 da 0f 82 47 01 00 00 48 c7 c7 00 00 00 80 48 2b 3d ef 98 c1 00 49 01 fa 49 c1 ea 0c 49 c1 e2 06 4c 03 15 cd 98 c1 00 <49> 8b 42 20 48 8d 50 ff a8 01 4c 0f 45 d2 49 8b 52 20 48 8d 42 [36488.961040] RIP: kfree+0x53/0x190 RSP: ffffa003ce10fd30 [36488.962714] CR2: ffffdf3cd60001a0 [36488.964377] ---[ end trace 46732cc399d66b31 ]--- ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: linux-image-4.13.0-17-lowlatency 4.13.0-17.20 ProcVersionSignature: Ubuntu 4.13.0-17.20-lowlatency 4.13.8 Uname: Linux 4.13.0-17-lowlatency x86_64 ApportVersion: 2.20.7-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: bnoordhuis 1664 F.... pulseaudio /dev/snd/controlC0: bnoordhuis 1664 F.... pulseaudio CurrentDesktop: GNOME Date: Mon Nov 27 13:47:25 2017 HibernationDevice: RESUME=UUID=9259e504-5786-4612-b8b4-315af58f8159 InstallationDate: Installed on 2012-07-20 (1955 days ago) InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" -
