I tested with linux-headers-4.4.0-040400 / linux- headers-4.4.0-040400-generic / linux-image-4.4.0-040400-generic 4.4.0-040400.201601101930. The kernel lockups did *not* reproduce.
Two caveats: (1) I did get this kernel warning in the log: Jan 21 18:00:08 e104462 kernel: [ 171.577000] ------------[ cut here ]------------ Jan 21 18:00:08 e104462 kernel: [ 171.577005] WARNING: CPU: 6 PID: 14136 at /home/kernel/COD/linux/kernel/signal.c:2072 get_signal+0x597/0x600() Jan 21 18:00:08 e104462 kernel: [ 171.577006] Modules linked in: rfcomm bnep bluetooth nfsd auth_rpcgss nfs_acl nfs binfmt_misc lockd grace sunrpc fscache drbg ansi_cprng snd_hda_codec_hdmi intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm dm_crypt irqbypass crct10dif_pclmul crc32_pclmul aesni_intel aes_x86_64 lrw snd_hda_codec_realtek snd_hda_codec_generic gf128mul glue_helper ablk_helper snd_hda_intel cryptd snd_hda_codec snd_hda_core snd_hwdep input_leds pl2303 snd_pcm usbserial snd_seq_midi snd_seq_midi_event snd_rawmidi snd_seq snd_seq_device snd_timer snd 8250_fintek soundcore mei_me mei shpchp ie31200_edac lpc_ich ppdev edac_core serio_raw mac_hid parport_pc lp parport hid_generic usbhid hid uas usb_storage nouveau mxm_wmi i2c_algo_bit ttm drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops e1000e drm ahci psmouse libahci ptp pps_core wmi fjes video Jan 21 18:00:08 e104462 kernel: [ 171.577037] CPU: 6 PID: 14136 Comm: block-z8iSdZiRK Not tainted 4.4.0-040400-generic #201601101930 Jan 21 18:00:08 e104462 kernel: [ 171.577038] Hardware name: LENOVO 32281S1/MAHOBAY, BIOS 9SKT71AUS 07/02/2013 Jan 21 18:00:08 e104462 kernel: [ 171.577039] 0000000000000000 00000000a495bf0f ffff88040afdbd20 ffffffff813c8d94 Jan 21 18:00:08 e104462 kernel: [ 171.577040] 0000000000000000 ffff88040afdbd58 ffffffff8107dba2 0000000000000000 Jan 21 18:00:08 e104462 kernel: [ 171.577042] ffff88040afdbe38 0000000000008000 ffff88040afdbf58 ffff880405d58000 Jan 21 18:00:08 e104462 kernel: [ 171.577043] Call Trace: Jan 21 18:00:08 e104462 kernel: [ 171.577046] [<ffffffff813c8d94>] dump_stack+0x44/0x60 Jan 21 18:00:08 e104462 kernel: [ 171.577049] [<ffffffff8107dba2>] warn_slowpath_common+0x82/0xc0 Jan 21 18:00:08 e104462 kernel: [ 171.577050] [<ffffffff8107dcea>] warn_slowpath_null+0x1a/0x20 Jan 21 18:00:08 e104462 kernel: [ 171.577051] [<ffffffff8108d0e7>] get_signal+0x597/0x600 Jan 21 18:00:08 e104462 kernel: [ 171.577053] [<ffffffff81016517>] do_signal+0x37/0x6f0 Jan 21 18:00:08 e104462 kernel: [ 171.577055] [<ffffffff817f9925>] ? schedule+0x35/0x80 Jan 21 18:00:08 e104462 kernel: [ 171.577057] [<ffffffff81080b96>] ? do_exit+0x736/0xab0 Jan 21 18:00:08 e104462 kernel: [ 171.577058] [<ffffffff81021272>] ? __switch_to_xtra+0xe2/0x1b0 Jan 21 18:00:08 e104462 kernel: [ 171.577061] [<ffffffff8100320c>] exit_to_usermode_loop+0x8c/0xd0 Jan 21 18:00:08 e104462 kernel: [ 171.577062] [<ffffffff81003c2e>] syscall_return_slowpath+0x4e/0x60 Jan 21 18:00:08 e104462 kernel: [ 171.577064] [<ffffffff817fdb18>] int_ret_from_sys_call+0x25/0x8f Jan 21 18:00:08 e104462 kernel: [ 171.577065] ---[ end trace 1c1af43c0c2249f3 ]--- but it seems to be a completely different thing from the lockup back traces seen with the 3.13 kernel. (2) rr complains: 1134: [FATAL /home/petmay01/src/rr/src/Monkeypatcher.cc:660:patch_after_exec_arch<rr::X86Arch>() errno: 0 'Success'] 1134: -> Failed to monkeypatch vdso: your __kernel_vsyscall() wasn't recognized. 1134: Syscall buffering is now effectively disabled. If you're OK with 1134: running rr without syscallbuf, then run the recorder passing the 1134: --no-syscall-buffer arg. 1134: If you're *not* OK with that, file an issue. which indicates that it's not happy with running under a 4.4 kernel in some way, and the code being run won't be the same as it was under the 3.13 kernel. (I filed https://github.com/mozilla/rr/issues/1627 against rr about that.) ** Tags added: kernel-fixed-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1535307 Title: running 'rr' make check causes kernel "hard LOCKUP" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1535307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
