I was using perf a few hours before this happened, so it might be a perf issue. I'm pretty sure this was fixed in a more recent kernel. Please try 2.6.38-rc8, which was submitted for testing today: https://admin.fedoraproject.org/updates/kernel-2.6.38-0.rc8.git0.1.fc15 Thanks, I'm already running it. No problems yet, and I've perfed quite a bit. I am running 2.6.38-0.rc8.git0.2 now and just had: [17609.564972] ------------[ cut here ]------------ [17609.569598] WARNING: at arch/x86/kernel/dumpstack_64.c:129 dump_trace+0x2bc/0x308() [17609.577246] Hardware name: X8DTH-i/6/iF/6F [17609.581342] Perf: bad frame pointer = (null) in callchain [17609.587608] Modules linked in: fuse crc32c_intel oprofile w83627ehf hwmon_vid adm1021 ipmi_devintf ipmi_si ipmi_msghandler dm_round_robin dm_multipath ib_ipoib rdma_ucm ib_ucm ib_uverbs ib_umad rdma_cm ib_cm iw_cm ib_addr ipv6 ib_sa mlx4_ib ib_mad ib_core mlx4_en microcode ghes hed ses i2c_i801 i7core_edac ioatdma igb i2c_core enclosure edac_core dca iTCO_wdt mlx4_core iTCO_vendor_support uas mpt2sas usb_storage scsi_transport_sas raid_class [last unloaded: oprofile] [17609.629722] Pid: 11410, comm: sysprof Not tainted 2.6.38-0.rc8.git0.2.fc14.x86_64 #1 [17609.637459] Call Trace: [17609.639908] <IRQ> [<ffffffff81059357>] ? warn_slowpath_common+0x85/0x9d [17609.646714] [<ffffffff81059412>] ? warn_slowpath_fmt+0x46/0x48 [17609.652633] [<ffffffff81490a26>] ? bad_to_user+0x70/0x764 [17609.658119] [<ffffffff8100d5b4>] ? dump_trace+0x2bc/0x308 [17609.663605] [<ffffffff8107b578>] ? timekeeping_get_ns+0x1b/0x3d [17609.669608] [<ffffffff8101b4a8>] ? perf_callchain_kernel+0x5a/0x5c [17609.675874] [<ffffffff810db732>] ? perf_prepare_sample+0xf2/0x1d2 [17609.682049] [<ffffffff810db96f>] ? __perf_event_overflow+0x15d/0x1ab [17609.688489] [<ffffffff81010f89>] ? paravirt_read_tsc+0x9/0xd [17609.694233] [<ffffffff810114a7>] ? native_sched_clock+0x35/0x37 [17609.700235] [<ffffffff810114b2>] ? sched_clock+0x9/0xd [17609.705461] [<ffffffff81078ac8>] ? sched_clock_cpu+0x42/0xc6 [17609.711206] [<ffffffff810dbfdc>] ? perf_event_overflow+0x14/0x16 [17609.717298] [<ffffffff810dc070>] ? perf_swevent_hrtimer+0x92/0xde [17609.723477] [<ffffffff810a6591>] ? audit_syscall_exit+0x0/0x14c [17609.729482] [<ffffffff8123f2bb>] ? timerqueue_del+0x59/0x6a [17609.735141] [<ffffffff810765d8>] ? __remove_hrtimer+0x62/0x6e [17609.740969] [<ffffffff81076854>] ? __run_hrtimer+0xb9/0x13f [17609.746626] [<ffffffff810dbfde>] ? perf_swevent_hrtimer+0x0/0xde [17609.752715] [<ffffffff81077046>] ? hrtimer_interrupt+0xd1/0x1b0 [17609.758713] [<ffffffff81049126>] ? account_system_vtime+0x6f/0x8c [17609.764892] [<ffffffff8148f026>] ? smp_apic_timer_interrupt+0x79/0x8c [17609.771418] [<ffffffff8100b613>] ? apic_timer_interrupt+0x13/0x20 [17609.777592] <EOI> [<ffffffff8112bfd4>] ? vfs_read+0xbc/0xfc [17609.783357] [<ffffffff810a6591>] ? audit_syscall_exit+0x0/0x14c [17609.789360] [<ffffffff8100ad74>] ? sysret_audit+0x16/0x20 [17609.794836] ---[ end trace 14962c7de7a584a6 ]--- I was running sysprof for a while, that might have triggered it.
