[Kernel-packages] [Bug 1712831] Missing required logs.
This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window: apport-collect 1712831 and then change the status of the bug to 'Confirmed'. If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'. This change has been made by an automated script, maintained by the Ubuntu Kernel Team. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1712831 Title: 4.12.0-11-generic - crashing in infrastructure on i386 openvswitch tests Status in linux package in Ubuntu: Incomplete Bug description: Hi, this seems to me to be a kernel crash of some sorts. Somewhat in the spirit of older bugs: - bug 1630940 - bug 1630578 Xnox asked me to look into a hang on openvswitch dep8 tests. What I found initially was in the log just "ERROR: Removing temporary files on testbed timed out" That message brought me to the two bugs above. But in there I read that this was the infra running dep8 crashing. So for a better bug report I tried to reproduce locally and that actually seems to work very reliable. To reproduce do: $ autopkgtest-buildvm-ubuntu-cloud -a i386 -r artful -s 10G $ pull-lp-source openvswitch $ autopkgtest --apt-upgrade --shell --no-built-binaries openvswitch_2.8.0~git20170809.7aa47a19d-0ubuntu1.dsc -- qemu ~/work/autopkgtest-artful-i386.img # This guest currently will crash after a while of testing But with that running you can attach to the console and monitor of that guest. For example: $ sudo nc -U /tmp/autopkgtest-virt-qemu.*/ttyS0 That gave me a crash on the hang which kind of matches the older bugs, here the console: [ 54.256253] BUG: unable to handle kernel NULL pointer dereference at (null) [ 54.257156] IP: add_grec+0x28/0x440 [ 54.257553] *pdpt = 1a869001 *pde = [ 54.257555] [ 54.258338] Oops: [#1] SMP [ 54.258638] Modules linked in: veth openvswitch nf_conntrack_ipv6 nf_nat_ipv6 nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat_ipv4 nf_defrag_ipv6 nf_nat nf_conntrack libcrc32c 9p fscache ppdev kvm_intel kvm irqbypass joydev input_leds serio_raw 9pnet_virtio parport_pc 9pnet parport qemu_fw_cfg i2c_piix4 mac_hid ip_tables x_tables autofs4 btrfs xor raid6_pq psmouse virtio_blk virtio_net floppy pata_acpi [ 54.261891] CPU: 0 PID: 0 Comm: swapper/0 Tainted: GW 4.12.0-11-generic #12-Ubuntu [ 54.262715] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.1-1ubuntu1~cloud0 04/01/2014 [ 54.263610] task: c7b622c0 task.stack: c7b5a000 [ 54.264039] EIP: add_grec+0x28/0x440 [ 54.264378] EFLAGS: 00010202 CPU: 0 [ 54.264711] EAX: EBX: dd062540 ECX: 0006 EDX: dd062540 [ 54.265308] ESI: dd1e6e00 EDI: dd1e6e00 EBP: dbcc5f30 ESP: dbcc5ef0 [ 54.265793] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 54.266297] CR0: 80050033 CR2: CR3: 1e930d80 CR4: 06f0 [ 54.266885] Call Trace: [ 54.267120] [ 54.267349] mld_ifc_timer_expire+0xfe/0x250 [ 54.267754] ? mld_dad_timer_expire+0x50/0x50 [ 54.268173] call_timer_fn+0x30/0x120 [ 54.268524] ? mld_dad_timer_expire+0x50/0x50 [ 54.268942] ? mld_dad_timer_expire+0x50/0x50 [ 54.269364] run_timer_softirq+0x3c5/0x420 [ 54.269760] ? __softirqentry_text_start+0x8/0x8 [ 54.270198] __do_softirq+0xa9/0x245 [ 54.270539] ? __softirqentry_text_start+0x8/0x8 [ 54.270976] do_softirq_own_stack+0x24/0x30 [ 54.271373] [ 54.271611] irq_exit+0xad/0xb0 [ 54.271913] smp_apic_timer_interrupt+0x38/0x50 [ 54.272344] apic_timer_interrupt+0x39/0x40 [ 54.272745] EIP: native_safe_halt+0x5/0x10 [ 54.273139] EFLAGS: 0246 CPU: 0 [ 54.273624] EAX: EBX: ECX: 0001 EDX: [ 54.274000] ESI: EDI: c7b622c0 EBP: c7b5bf10 ESP: c7b5bf10 [ 54.274361] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0068 [ 54.274687] default_idle+0x1c/0xf0 [ 54.274896] arch_cpu_idle+0xe/0x10 [ 54.275286] default_idle_call+0x1e/0x30 [ 54.275787] do_idle+0x145/0x1c0 [ 54.276092] cpu_startup_entry+0x65/0x70 [ 54.276441] rest_init+0x62/0x70 [ 54.276718] start_kernel+0x3be/0x3d7 [ 54.276974] i386_start_kernel+0x9d/0xa1 [ 54.277260] startup_32_smp+0x16b/0x16d [ 54.277509] Code: 00 00 00 3e 8d 74 26 00 55 89 e5 57 56 53 89 c6 83 ec 34 89 4d e8 65 a1 14 00 00 00 89 45 f0 31 c0 8b 42 10 f6 42 48 08 89 45 cc <8b> 00 c7 45 ec 00 00 00 00 89 45 c8 89 f0 0f 85 b4 02 00 00 8b [ 54.279314] EIP: add_grec+0x28/0x440 SS:ESP: 0068:dbcc5ef0 [ 54.279829] CR2:
