I wrote: "PS: it's possible that that commit doesn't actually fix the underlying kernel crash, it just means that rr isn't triggering it any more, and that if you modified EFLAGS via the ptrace interface rather than r11 you'd get the crash back again." but looking at the kernel I think that is impossible, since the set_flags() function in arch/x86/kernel/ptrace.c sanitizes eflags if set via ptrace. The issue fixed by 29722cd4ef66 is that setting r11 in some situations would bypass the sanitizing.

(rr build-and-make-check instructions: https://github.com/mozilla/rr/wiki/Building-And- Installing) This is 3.13.0-74-generic #118-Ubuntu for x86_64. This is rr bug https://github.com/mozilla/rr/issues/1614 (which includes information about a Debian Jessie kernel crash initially and also the Ubuntu crash later on in the same report), but since crashing the kernel is a kernel bug I'm reporting that part here. kern.log reports: Jan 18 12:33:12 e104462 kernel: [ 367.805326] ------------[ cut here ]------------ Jan 18 12:33:12 e104462 kernel: [ 367.805333] WARNING: CPU: 2 PID: 4294 at /build/linux-_xRakU/linux-3.13.0/kernel/watchdog.c:245 watchdog_overflow_callback+0x 9c/0xd0() Jan 18 12:33:12 e104462 kernel: [ 367.805334] Watchdog detected hard LOCKUP on cpu 2 Jan 18 12:33:12 e104462 kernel: [ 367.805335] Modules linked in: pci_stub vboxpci(OX) vboxnetadp(OX) vboxnetflt(OX) vboxdrv(OX) bnep rfcomm bluetooth nfsd auth_rpcgss nfs_acl binfmt_misc nfs lockd sunrpc fscache dm_crypt snd_hda_codec_hdmi intel_rapl snd_hda_codec_realtek x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel snd_hda_intel snd_hda_codec kvm pl2303 usbserial snd_hwdep snd_pcm crct10dif_pclmul crc32_pclmul snd_page_alloc snd_seq_midi snd_seq_midi_event snd_rawmidi aesni_intel aes_x86_64 lrw snd_seq gf128mul glue_helper ablk_helper cryptd snd_seq_device serio_raw snd_timer lpc_ich snd soundcore mei_me mei shpchp mac_hid parport_pc ppdev lp parport hid_generic usbhid hid usb_storage nouveau mxm_wmi i2c_algo_bit ttm drm_kms_helper e1000e psmouse ahci drm ptp libahci pps_core video wmi Jan 18 12:33:12 e104462 kernel: [ 367.805365] CPU: 2 PID: 4294 Comm: rr:async_signal Tainted: G OX 3.13.0-74-generic #118-Ubuntu Jan 18 12:33:12 e104462 kernel: [ 367.805366] Hardware name: LENOVO 32281S1/MAHOBAY, BIOS 9SKT71AUS 07/02/2013 Jan 18 12:33:12 e104462 kernel: [ 367.805367] 0000000000000009 ffff8804033abc78 ffffffff81724b70 ffff8804033abcc0 Jan 18 12:33:12 e104462 kernel: [ 367.805369] ffff8804033abcb0 ffffffff810678bd ffff880407798000 0000000000000000 Jan 18 12:33:12 e104462 kernel: [ 367.805370] ffff8804033abde0 0000000000000000 ffff8804033abf58 ffff8804033abd10 Jan 18 12:33:12 e104462 kernel: [ 367.805372] Call Trace: Jan 18 12:33:12 e104462 kernel: [ 367.805376] [<ffffffff81724b70>] dump_stack+0x45/0x56 Jan 18 12:33:12 e104462 kernel: [ 367.805379] [<ffffffff810678bd>] warn_slowpath_common+0x7d/0xa0 Jan 18 12:33:12 e104462 kernel: [ 367.805380] [<ffffffff8106792c>] warn_slowpath_fmt+0x4c/0x50 Jan 18 12:33:12 e104462 kernel: [ 367.805382] [<ffffffff8110e3b0>] ? restart_watchdog_hrtimer+0x50/0x50 Jan 18 12:33:12 e104462 kernel: [ 367.805384] [<ffffffff8110e44c>] watchdog_overflow_callback+0x9c/0xd0 Jan 18 12:33:12 e104462 kernel: [ 367.805386] [<ffffffff811461ee>] __perf_event_overflow+0x8e/0x250 Jan 18 12:33:12 e104462 kernel: [ 367.805389] [<ffffffff810293e8>] ? x86_perf_event_set_period+0xe8/0x150 Jan 18 12:33:12 e104462 kernel: [ 367.805390] [<ffffffff81146d14>] perf_event_overflow+0x14/0x20 Jan 18 12:33:12 e104462 kernel: [ 367.805392] [<ffffffff8103084d>] intel_pmu_handle_irq+0x1ed/0x3f0 Jan 18 12:33:12 e104462 kernel: [ 367.805395] [<ffffffff8172ebdb>] perf_event_nmi_handler+0x2b/0x50 Jan 18 12:33:12 e104462 kernel: [ 367.805397] [<ffffffff8172e358>] nmi_handle.isra.2+0x88/0x180 Jan 18 12:33:12 e104462 kernel: [ 367.805399] [<ffffffff8172e619>] do_nmi+0x1c9/0x3e0 Jan 18 12:33:12 e104462 kernel: [ 367.805400] [<ffffffff8172d6ea>] nmi+0x5a/0xbf Jan 18 12:33:12 e104462 kernel: [ 367.805402] ---[ end trace 1511edbd209fafac ]--- followed a little later by Jan 18 12:33:33 e104462 kernel: [ 392.175012] BUG: soft lockup - CPU#1 stuck for 23s!
