apport information ** Tags added: apport-collected
** Description changed: I started a new EC2 instance of Ubuntu 11.10 Oneiric using ami-a7f539ce in us-east-1. About two days later, it became non-responsive to ssh, http, etc. I found the following kernel oops stack trace in /var/log/syslog. I stopped/started the instance to get it running again, so the attached reports may not be the exact hardware on which it failed. --------------------------------------------------------------------------------- Oct 31 13:44:25 a111 kernel: [145151.542222] BUG: unable to handle kernel paging request at f57ba9a1 Oct 31 13:44:25 a111 kernel: [145151.542248] IP: [<c0216200>] swap_count_continued.isra.17+0x190/0x1b0 Oct 31 13:44:25 a111 kernel: [145151.542268] *pdpt = 0000000021498027 *pde = 00000000009ba067 *pte = 0000000000000000 Oct 31 13:44:25 a111 kernel: [145151.542287] Oops: 0002 [#1] SMP Oct 31 13:44:25 a111 kernel: [145151.542299] Modules linked in: xt_multiport iptable_filter ip_tables x_tables xfs acpiphp Oct 31 13:44:25 a111 kernel: [145151.542333] Oct 31 13:44:25 a111 kernel: [145151.542340] Pid: 5942, comm: apache2 Not tainted 3.0.0-12-virtual #20-Ubuntu Oct 31 13:44:25 a111 kernel: [145151.542356] EIP: 0061:[<c0216200>] EFLAGS: 00010246 CPU: 0 Oct 31 13:44:25 a111 kernel: [145151.542365] EIP is at swap_count_continued.isra.17+0x190/0x1b0 Oct 31 13:44:25 a111 kernel: [145151.542374] EAX: f57ba9a1 EBX: 000009a1 ECX: ec6330c0 EDX: 0000003e Oct 31 13:44:25 a111 kernel: [145151.542384] ESI: ecc500a0 EDI: 0000003e EBP: e1497d60 ESP: e1497d50 Oct 31 13:44:25 a111 kernel: [145151.542394] DS: 007b ES: 007b FS: 00d8 GS: 00e0 SS: 0069 Oct 31 13:44:25 a111 kernel: [145151.542402] Process apache2 (pid: 5942, ti=e1496000 task=e1fed940 task.ti=e1496000) Oct 31 13:44:25 a111 kernel: [145151.542413] Stack: Oct 31 13:44:25 a111 kernel: [145151.542419] ed3e55e0 eae82300 000239a1 fffffff4 e1497d90 c02162ed 00000001 9375b045 Oct 31 13:44:25 a111 kernel: [145151.542449] 80000000 d30f6068 0000003e edc31000 3e400194 000239a1 00000000 e149c070 Oct 31 13:44:25 a111 kernel: [145151.542479] e1497d9c c0218bec 00100073 e1497e28 c0207483 9375b045 80000000 e1fed940 Oct 31 13:44:25 a111 kernel: [145151.542509] Call Trace: Oct 31 13:44:25 a111 kernel: [145151.542519] [<c02162ed>] __swap_duplicate+0xcd/0x130 Oct 31 13:44:25 a111 kernel: [145151.542530] [<c0218bec>] swap_duplicate+0x1c/0x50 Oct 31 13:44:25 a111 kernel: [145151.542541] [<c0207483>] copy_pte_range+0x373/0x480 Oct 31 13:44:25 a111 kernel: [145151.542552] [<c0208e2f>] copy_page_range+0x15f/0x2d0 Oct 31 13:44:25 a111 kernel: [145151.542565] [<c014df48>] dup_mmap+0x1d8/0x310 Oct 31 13:44:25 a111 kernel: [145151.542575] [<c014e835>] dup_mm+0xd5/0x220 Oct 31 13:44:25 a111 kernel: [145151.542586] [<c0144f71>] ?
