No, I'm not using the latest v5.10.250. I tested on two versions --- v5.10.174 and v5.10.239 --- and I still see the issue on both. For your reference, here is a grep from my .config showing most of the tracing options I enabled while troubleshooting this issue. mona_pc$ grep "TRACE\|SYSCALL\|EVENT\|PROBE" .config CONFIG_HAVE_ARCH_AUDITSYSCALL=y CONFIG_GENERIC_TIME_VSYSCALL=y CONFIG_GENERIC_CLOCKEVENTS=y CONFIG_GENERIC_CLOCKEVENTS_BROADCAST=y CONFIG_SYSCTL_EXCEPTION_TRACE=y CONFIG_SGETMASK_SYSCALL=y CONFIG_SYSFS_SYSCALL=y CONFIG_EVENTFD=y CONFIG_ADVISE_SYSCALLS=y # CONFIG_BPF_SYSCALL is not set CONFIG_HAVE_PERF_EVENTS=y CONFIG_PERF_EVENTS=y CONFIG_VM_EVENT_COUNTERS=y CONFIG_TRACEPOINTS=y CONFIG_FSL_EMB_PERF_EVENT=y CONFIG_FSL_EMB_PERF_EVENT_E500=y CONFIG_STACKTRACE_SUPPORT=y CONFIG_TRACE_IRQFLAGS_SUPPORT=y CONFIG_ARCH_SUPPORTS_UPROBES=y CONFIG_ARCH_CPU_PROBE_RELEASE=y CONFIG_KPROBES=y CONFIG_OPTPROBES=y CONFIG_KRETPROBES=y CONFIG_HAVE_KPROBES=y CONFIG_HAVE_KRETPROBES=y CONFIG_HAVE_OPTPROBES=y CONFIG_HAVE_KPROBES_ON_FTRACE=y CONFIG_HAVE_ARCH_TRACEHOOK=y CONFIG_HAVE_PERF_EVENTS_NMI=y # CONFIG_LOCK_EVENT_COUNTS is not set # CONFIG_NF_CONNTRACK_EVENTS is not set # CONFIG_NETFILTER_XT_TARGET_TRACE is not set CONFIG_PCI_SYSCALL=y CONFIG_UEVENT_HELPER=y CONFIG_UEVENT_HELPER_PATH="/sbin/hotplug" CONFIG_PREVENT_FIRMWARE_BUILD=y # CONFIG_TEST_ASYNC_DRIVER_PROBE is not set CONFIG_GENERIC_CPU_AUTOPROBE=y CONFIG_PROC_EVENTS=y # CONFIG_MTD_JEDECPROBE is not set CONFIG_MTD_GEN_PROBE=y # CONFIG_TRACE_SINK is not set CONFIG_STACKTRACE=y # CONFIG_RCU_TRACE is not set CONFIG_NOP_TRACER=y CONFIG_HAVE_FUNCTION_TRACER=y CONFIG_HAVE_FUNCTION_GRAPH_TRACER=y CONFIG_HAVE_DYNAMIC_FTRACE=y CONFIG_HAVE_FTRACE_MCOUNT_RECORD=y CONFIG_HAVE_SYSCALL_TRACEPOINTS=y CONFIG_TRACER_MAX_TRACE=y CONFIG_TRACE_CLOCK=y CONFIG_EVENT_TRACING=y CONFIG_CONTEXT_SWITCH_TRACER=y CONFIG_GENERIC_TRACER=y CONFIG_FTRACE=y CONFIG_FUNCTION_TRACER=y CONFIG_FUNCTION_GRAPH_TRACER=y CONFIG_DYNAMIC_FTRACE=y CONFIG_STACK_TRACER=y # CONFIG_IRQSOFF_TRACER is not set CONFIG_SCHED_TRACER=y # CONFIG_HWLAT_TRACER is not set CONFIG_FTRACE_SYSCALLS=y CONFIG_TRACER_SNAPSHOT=y # CONFIG_TRACER_SNAPSHOT_PER_CPU_SWAP is not set CONFIG_BLK_DEV_IO_TRACE=y CONFIG_KPROBE_EVENTS=y CONFIG_KPROBE_EVENTS_ON_NOTRACE=y # CONFIG_UPROBE_EVENTS is not set CONFIG_DYNAMIC_EVENTS=y CONFIG_PROBE_EVENTS=y CONFIG_FTRACE_MCOUNT_RECORD=y # CONFIG_SYNTH_EVENTS is not set # CONFIG_TRACE_EVENT_INJECT is not set # CONFIG_TRACEPOINT_BENCHMARK is not set # CONFIG_TRACE_EVAL_MAP_FILE is not set # CONFIG_FTRACE_STARTUP_TEST is not set # CONFIG_KPROBE_EVENT_GEN_TEST is not set CONFIG_CC_HAS_SANCOV_TRACE_PC=y -- Mohammad
