The "No such file or directory" is not coming as a result of the exec of the trace-cmd function, but rather is part of the output of the command itself, which is invoked as this example: trace-cmd report /tmp/crash.trace_dat.Xb0wy6 If I start ftracing "wakeup" on rhel7, it shows the "No such file or directory" output from "trace-cmd report" before it shows the ftrace data, so apparently that's not the bug seen in the pegas kernel: crash> trace show trace-cmd: No such file or directory [nfsd:read_start] function __builtin_constant_p not defined [nfsd:read_opened] function __builtin_constant_p not defined [nfsd:read_io_done] function __builtin_constant_p not defined [nfsd:read_done] function __builtin_constant_p not defined [nfsd:write_start] function __builtin_constant_p not defined [nfsd:write_opened] function __builtin_constant_p not defined [nfsd:write_io_done] function __builtin_constant_p not defined [nfsd:write_done] function __builtin_constant_p not defined [sunrpc:xprt_lookup_rqst] function __builtin_constant_p not defined [sunrpc:xprt_transmit] function __builtin_constant_p not defined [sunrpc:xprt_complete_rqst] function __builtin_constant_p not defined [sunrpc:xs_tcp_data_recv] function __builtin_constant_p not defined [sunrpc:svc_recv] function __builtin_constant_p not defined [sunrpc:svc_defer] function __builtin_constant_p not defined [sunrpc:svc_drop] function __builtin_constant_p not defined [sunrpc:svc_process] function __builtin_constant_p not defined [sunrpc:svc_send] function __builtin_constant_p not defined unknown op '->' [sunrpc:svc_xprt_do_enqueue] unknown op '->' unknown op '->' [sunrpc:svc_handle_xprt] unknown op '->' [sunrpc:svc_drop_deferred] function __builtin_constant_p not defined [sunrpc:svc_revisit_deferred] function __builtin_constant_p not defined [libata:ata_qc_complete_internal] function libata_trace_parse_qc_flags not defined [libata:ata_qc_complete_failed] function libata_trace_parse_qc_flags not defined [libata:ata_qc_complete_done] function libata_trace_parse_qc_flags not defined [libata:ata_eh_link_autopsy] function libata_trace_parse_eh_action not defined [libata:ata_eh_link_autopsy_qc] function libata_trace_parse_qc_flags not defined [ras:extlog_mem_event] function cper_severity_str not defined [ras:mc_event] function mc_event_error_type not defined [xen:xen_mmu_set_pte] function sizeof not defined [xen:xen_mmu_set_pte_atomic] function sizeof not defined [xen:xen_mmu_set_domain_pte] function sizeof not defined [xen:xen_mmu_set_pte_at] function sizeof not defined [xen:xen_mmu_set_pmd] function sizeof not defined [xen:xen_mmu_set_pud] function sizeof not defined [xen:xen_mmu_set_pgd] function sizeof not defined [xen:xen_mmu_ptep_modify_prot_start] function sizeof not defined [xen:xen_mmu_ptep_modify_prot_commit] function sizeof not defined cpus=2 <idle>-0 [000] 6375.998685: wakeup: 0:120:0 ==+ 10:0:0 [000] <idle>-0 [000] 6375.998687: function: ttwu_do_activate.constprop.92 <idle>-0 [000] 6375.998687: function: task_woken_rt <idle>-0 [000] 6375.998687: function: _raw_spin_unlock_irqrestore <idle>-0 [000] 6375.998687: function: ktime_get <idle>-0 [000] 6375.998687: function: hrtimer_forward <idle>-0 [000] 6375.998688: function: _raw_spin_lock <idle>-0 [000] 6375.998688: function: enqueue_hrtimer <idle>-0 [000] 6375.998689: function: __hrtimer_get_next_event <idle>-0 [000] 6375.998689: function: tick_program_event <idle>-0 [000] 6375.998689: function: clockevents_program_event <idle>-0 [000] 6375.998690: function: ktime_get <idle>-0 [000] 6375.998690: function: lapic_next_event <idle>-0 [000] 6375.998693: function: irq_exit <idle>-0 [000] 6375.998693: function: idle_cpu <idle>-0 [000] 6375.998693: function: ...
