Then we reset the box. The logs below are from /var/log/kern.log It's not reproducible at the moment. The issue happened when we tried to stop a VM (qemu-system-x86) hosted on the box via OpenNebula VM management web interface. Is there a way to figure out if this is a known issue that fixed on later kernel version? root@node-101:~# cat /proc/version_signature Ubuntu 3.13.0-32.57-generic 3.13.11.4 root@node-101:~# cat /etc/issue Ubuntu 14.04.1 LTS \n \l Mar 5 15:29:22 node-101 kernel: [18293149.767254] general protection fault: 0000 [#1] SMP Mar 5 15:29:22 node-101 kernel: [18293149.810640] Modules linked in: ipmi_devintf ipmi_si nfnetlink bluetooth ebtable_filter vhost_net vhost macvtap macvlan nbd ipt_MASQUERADE iptable_nat nf_nat_ ipv4 nf_nat nf_conntrack_ipv4 nf_defrag_ipv4 xt_conntrack nf_conntrack ipt_REJECT xt_CHECKSUM iptable_mangle xt_tcpudp ip6table_filter ip6_tables iptable_filter ip_tables ebtable_nat ebtables x_ta bles bridge stp llc nfsd auth_rpcgss nfs_acl nfs lockd sunrpc fscache x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel gpi o_ich aes_x86_64 sb_edac lrw gf128mul edac_core glue_helper mei_me ablk_helper ioatdma mei joydev wmi cryptd lpc_ich mac_hid xfs libcrc32c lp parport raid10 raid456 async_raid6_recov async_memcpy async_pq async_xor async_tx xor raid6_pq raid0 multipath linear raid1 igb i2c_algo_bit isci dca hid_generic libsas usbhid ptp hid ahci libahci scsi_transport_sas pps_core [last unloaded: ipmi_si] Mar 5 15:29:22 node-101 kernel: [18293150.361734] CPU: 18 PID: 16236 Comm: qemu-system-x86 Not tainted 3.13.0-32-generic #57-Ubuntu Mar 5 15:29:22 node-101 kernel: [18293150.448654] Hardware name: Supermicro SYS-F627R3-RTB+/X9DRFR, BIOS 3.0a 01/29/2014 Mar 5 15:29:22 node-101 kernel: [18293150.539953] task: ffff881026eadfc0 ti: ffff8813c7a84000 task.ti: ffff8813c7a84000 Mar 5 15:29:22 node-101 kernel: [18293150.629011] RIP: 0010:[<ffffffff811a4383>] [<ffffffff811a4383>] __kmalloc_node_track_caller+0x173/0x290 Mar 5 15:29:22 node-101 kernel: [18293150.740566] RSP: 0018:ffff8813c7a85bb8 EFLAGS: 00010246 Mar 5 15:29:22 node-101 kernel: [18293150.795788] RAX: 0000000000000000 RBX: ffff881dc796cd00 RCX: 00000000012267b0 Mar 5 15:29:22 node-101 kernel: [18293150.904469] RDX: 00000000012267af RSI: 0000000000000000 RDI: 00000000000172a0 Mar 5 15:29:22 node-101 kernel: [18293151.013444] RBP: ffff8813c7a85c00 R08: ffff88207fcd72a0 R09: ffff88103f803500 Mar 5 15:29:22 node-101 kernel: [18293151.121781] R10: ffff88103f803500 R11: 0000000000000293 R12: 00000000000106d0 Mar 5 15:29:22 node-101 kernel: [18293151.230534] R13: 00000000000002c0 R14: 2d70757465732220 R15: 00000000ffffffff Mar 5 15:29:22 node-101 kernel: [18293151.337326] FS: 00007f772b0ab980(0000) GS:ffff88207fcc0000(0000) knlGS:0000000000000000 Mar 5 15:29:22 node-101 kernel: [18293151.441748] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Mar 5 15:29:22 node-101 kernel: [18293151.484866] CR2: 00007f7473600000 CR3: 0000002015c11000 CR4: 00000000001427e0 Mar 5 15:29:22 node-101 kernel: [18293151.569286] Stack: Mar 5 15:29:22 node-101 kernel: [18293151.613617] ffff8820217c9808 ffff880b00000000 ffff88103f803500 ffffffff81610e7e Mar 5 15:29:22 node-101 kernel: [18293151.717684] ffff881dc796cd00 ffff8813c7a85c5f 00000000000004d0 00000000000002c0 Mar 5 15:29:22 node-101 kernel: [18293151.818459] 00000000ffffffff ffff8813c7a85c40 ffffffff816104f1 ffffffff81610e4e Mar 5 15:29:22 node-101 kernel: [18293151.923644] Call Trace: Mar 5 15:29:22 node-101 kernel: [18293151.974362] [<ffffffff81610e7e>] ?
