My setup is a Rackspace Cloud Server running Ubuntu 13.04 with kernel 3.8.0-30-generic #44-Ubuntu SMP Thu Aug 22 20:52:24 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux > > The cloud server uses Xen Hypervisor. > > Hiphopvm is compiled from source using the github repo. When running hhvm from the command line (without any options or php application) the system immediately crashes, throwing linux into a kernel panic and thus death. > And what happens if you run 'perf' by itself? > I have reported this issue on hiphop github issue page: > > https://github.com/facebook/hiphop-php/issues/1065 > > I am not sure if this is a linux kernel bug or a xen hypervisor bug: > > The output of /var/log/syslog: > > Sep 18 10:55:58 web kernel: [92118.674736] general protection fault: 0000 [#1] SMP > Sep 18 10:55:58 web kernel: [92118.674754] Modules linked in: xenfs(F) xen_privcmd(F) xt_tcpudp(F) nf_conntrack_ipv4(F) nf_defrag_ipv4(F) xt_state(F) nf_conntrack(F) xt_comment(F) iptable_filter(F) ip_tables(F) x_tables(F) microcode(F) lp(F) parport(F) > Sep 18 10:55:58 web kernel: [92118.674781] CPU 0 > Sep 18 10:55:58 web kernel: [92118.674787] Pid: 5020, comm: hhvm Tainted: GF 3.8.0-30-generic #44-Ubuntu > Sep 18 10:55:58 web kernel: [92118.674795] RIP: e030:[] [] native_read_pmc+0x6/0x20 > Sep 18 10:55:58 web kernel: [92118.674809] RSP: e02b:ffff8800026b9d20 EFLAGS: 00010083 > Sep 18 10:55:58 web kernel: [92118.674814] RAX: ffffffff81c1bd80 RBX: 0000000000000000 RCX: 0000000000000000 > Sep 18 10:55:58 web kernel: [92118.674819] RDX: 0000000000005f6c RSI: ffff8800f7c81900 RDI: 0000000000000000 > Sep 18 10:55:58 web kernel: [92118.674824] RBP: ffff8800026b9d20 R08: 00000000000337d8 R09: ffff8800e933dcc0 > Sep 18 10:55:58 web kernel: [92118.674830] R10: 00007fff2d3caea0 R11: 0000000000000246 R12: ffff8800f87ecc00 > Sep 18 10:55:58 web kernel: [92118.674835] R13: ffff800000000001 R14: ffff8800f87ecd70 R15: 0000000000000010 > Sep 18 10:55:58 web kernel: [92118.674844] FS: 00007f43d4c9b180(0000) GS:ffff8800ffc00000(0000) knlGS:0000000000000000 > Sep 18 10:55:58 web kernel: [92118.674850] CS: e033 DS: 0000 ES: 0000 CR0: 000000008005003b > Sep 18 10:55:58 web kernel: [92118.674855] CR2: 000000000105ebc0 CR3: 00000000025cd000 CR4: 0000000000000660 > Sep 18 10:55:58 web kernel: [92118.674861] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 > Sep 18 10:55:58 web kernel: [92118.674867] DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 > Sep 18 10:55:58 web kernel: [92118.674872] Process hhvm (pid: 5020, threadinfo ffff8800026b8000, task ffff8800f7cfc5c0) > Sep 18 10:55:58 web kernel: [92118.674879] Stack: > Sep 18 10:55:58 web kernel: [92118.674882] ffff8800026b9d58 ffffffff81024625 0000000000000000 ffff8800f87ecc00 > Sep 18 10:55:58 web kernel: [92118.674893] ffff8800f7c8190c ffffffff811231a0 0000000000000005 ffff8800026b9d68 > Sep 18 10:55:58 web kernel: [92118.674902] ffffffff81024689 ffff8800026b9d90 ffffffff811232a6 00000000ffff02ff > Sep 18 10:55:58 web kernel: [92118.674911] Call Trace: > Sep 18 10:55:58 web kernel: [92118.674920] [] x86_perf_event_update+0x55/0xb0 > Sep 18 10:55:58 web kernel: [92118.674929] [] ? perf_read+0x2f0/0x2f0 > Sep 18 10:55:58 web kernel: [92118.674936] [] x86_pmu_read+0x9/0x10 > Sep 18 10:55:58 web kernel: [92118.674942] [] __perf_event_read+0x106/0x110 > Sep 18 10:55:58 web kernel: [92118.674951] [] smp_call_function_single+0x147/0x170 > Sep 18 10:55:58 web kernel: [92118.674959] [] ? perf_mmap+0x2f0/0x2f0 > Sep 18 10:55:58 web kernel: [92118.674966] [] perf_event_read+0x10a/0x110 > Sep 18 10:55:58 web kernel: [92118.674972] [] ? perf_mmap+0x2f0/0x2f0 > Sep 18 10:55:58 web kernel: [92118.674979] [] perf_event_reset+0xd/0x20 > Sep 18 10:55:58 web kernel: [92118.674987] [] perf_event_for_each_child+0x38/0xa0 > Sep 18 10:55:58 web kernel: [92118.674994] [] ? perf_mmap+0x2f0/0x2f0 > Sep 18 10:55:58 web kernel: [92118.675001] [] perf_ioctl+0xba/0x340 > Sep 18 10:55:58 web kernel: [92118.675009] [] ? fd_install+0x25/0x30 > Sep 18 10:55:58 web kernel: [92118.675016] [] do_vfs_ioctl+0x99/0x570 > Sep 18 10:55:58 web kernel: [92118.675023] [] sys_ioctl+0x91/0xb0 > Sep 18 10:55:58 web kernel: [92118.675031] [] system_call_fastpath+0x1a/0x1f > Sep 18 10:55:58 web kernel: [92118.675036] Code: 00 00 00 00 00 55 89 f9 48 89 e5 0f 32 31 ff 89 c0 48 c1 e2 20 89 3e 48 09 c2 48 89 d0 5d c3 66 0f 1f 44 00 00 55 89 f9 48 89 e5 <0f> 33 89 c0 48 c1 e2 20 48 09 c2 48 89 d0 5d c3 66 2e 0f 1f 84 > Sep 18 10:55:58 web kernel: [92118.675103] RIP [] native_read_pmc+0x6/0x20 > Sep 18 10:55:58 web kernel: [92118.675110] RSP > Sep 18 10:55:58 web kernel: [92118.675118] ---[ end trace 1a73231ba5f74716 ]--- > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xen.org > http://lists.xen.org/xen-devel
