Public bug reported: Running in Virtualbox as a guest in a Macbook Pro, I'm running into a reliably-reproducible kernel oops on Ubuntu 16.04 with Linux 4.4.0-17-generic. The stack trace isn't always the same, although the error always happens in the same `update_blocked_averages` function. Here' one oops: ``` [ 56.972407] BUG: unable to handle kernel NULL pointer dereference at 0910 [ 57.076894] IP: [] update_blocked_averages+0x8d/0x520 [ 57.173751] PGD 0 [ 57.193537] Oops: [#1] SMP [ 57.245472] Modules linked in: veth xt_addrtype xt_conntrack ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 iptable_filter ip_tables x_tables nf_nat nf_conntrack bridge stp llc aufs ppdev crct10dif_pclmul crc32_pclmul snd_intel8x0 snd_ac97_codec aesni_intel ac97_bus aes_x86_64 snd_pcm lrw gf128mul snd_timer input_leds glue_helper ablk_helper snd cryptd joydev serio_raw soundcore i2c_piix4 8250_fintek mac_hid parport_pc lp parport autofs4 hid_generic usbhid ahci psmouse hid libahci pata_acpi e1000 video fjes [ 57.937239] CPU: 1 PID: 269 Comm: systemd-journal Not tainted 4.4.0-17-generic #33-Ubuntu [ 58.049743] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 58.189828] task: 8800d8f90dc0 ti: 8800da9a8000 task.ti: 8800da9a8000 [ 58.299087] RIP: 0010:[] [] update_blocked_averages+0x8d/0x520 [ 58.320327] RSP: 0018:8800da9abc70 EFLAGS: 00010046 [ 58.366603] RAX: RBX: 88020c3bae00 RCX: [ 58.514856] RDX: RSI: RDI: 0001 [ 58.612464] RBP: 8800da9abcc8 R08: afb504000afb5041 R09: [ 58.738629] R10: 0002 R11: R12: 0045 [ 58.885338] R13: R14: 8802198975c0 R15: 0001 [ 59.001563] FS: 7f7db7f6e840() GS:88021988() knlGS: [ 59.160653] CS: 0010 DS: ES: CR0: 80050033 [ 59.296218] CR2: 0910 CR3: 00020c3fd000 CR4: 000406e0 [ 59.418514] Stack: [ 59.458306] 000205f5 880219896d00 0086 afb504000afb5041 [ 59.580604] ad6001fe 0001 02f8 [ 59.720268] 00016d00 880219896d00 8800d8f91310 8800da9abd38 [ 59.848040] Call Trace: [ 59.902635] [] pick_next_task_fair+0x1e7/0x4f0 [ 59.992238] [] __schedule+0x125/0xa10 [ 60.030794] [] schedule+0x35/0x80 [ 60.074193] [] schedule_hrtimeout_range_clock+0x193/0x1b0 [ 60.134427] [] ? ep_scan_ready_list+0x1e7/0x1f0 [ 60.195234] [] ? __raw_callee_save___pv_queued_spin_unlock+0x11/0x20 [ 60.289354] [] schedule_hrtimeout_range+0x13/0x20 [ 60.325540] [] ep_poll+0x2c0/0x3d0 [ 60.328490] [] ? wake_up_q+0x70/0x70 [ 60.387888] [] SyS_epoll_wait+0xb8/0xd0 [ 60.502960] [] entry_SYSCALL_64_fastpath+0x16/0x71 [ 60.610213] Code: 24 08 49 b8 41 50 fb 0a 00 04 b5 af 4d 89 fe 0f 1f 44 00 00 44 8b 9b 24 01 00 00 45 85 db 0f 85 a0 03 00 00 48 8b 83 c8 00 00 00 <48> 8b 80 10 09 00 00 48 2b 83 18 01 00 00 48 8b 93 a0 00 00 00 [ 60.941287] RIP [] update_blocked_averages+0x8d/0x520 [ 61.111617] RSP [ 61.201406] CR2: 0910 [ 61.258351] ---[ end trace fe3df8ee7b476828 ]--- ``` Here's another one: ``` [ 154.454951] BUG: unable to handle kernel [ 154.455154] device vethe5e9554 entered promiscuous mode [ 154.455202] IPv6: ADDRCONF(NETDEV_UP): vethe5e9554: link is not ready [ 154.455203] docker0: port 1(vethe5e9554) entered forwarding state [ 154.455210] docker0: port 1(vethe5e9554) entered forwarding state [ 154.744305] NULL pointer dereference at 0910 [ 154.783574] IP: [] update_blocked_averages+0x8d/0x520 [ 154.784877] PGD 0 [ 154.785372] Oops: [#1] SMP [ 154.790654] Modules linked in: veth xt_addrtype xt_conntrack ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 iptable_filter ip_tables x_tables nf_nat nf_conntrack bridge stp llc aufs vboxsf(OE) ppdev crct10dif_pclmul crc32_pclmul aesni_intel snd_intel8x0 aes_x86_64 input_leds lrw snd_ac97_codec gf128mul glue_helper ac97_bus ablk_helper cryptd serio_raw vboxvideo(OE) joydev snd_pcm i2c_piix4 snd_timer drm 8250_fintek snd soundcore vboxguest(OE) parport_pc mac_hid lp parport autofs4 hid_generic usbhid ahci hid psmouse libahci e1000 pata_acpi video fjes [ 155.387419] CPU: 0 PID: 2043 Comm: systemd-udevd Tainted: G OE 4.4.0-17-generic #33-Ubuntu [ 155.546119] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 155.654775] task: 8800dbb3b700 ti: 88020da8c000 task.ti: 88020da8c000 [ 155.753906] RIP: 0010:[] [] update_blocked_averages+0x8d/0x520 [ 155.775805] RSP: :880219803df0 EFLAGS: 00010046 [ 155.811224] RAX: RBX: 8800db891200 RCX: 00
