Kernel image load event stackwalk not work

[0xhellord]

img_load event kernel stackwalk enabled by: CLASSIC_EVENT_ID event[1] = { 0 }; event[0].EventGuid = krabs::guids::image_load; event[0].Type = EVENT_TRACE_TYPE_LOAD; set_trace_information(TraceStackTracingInfo, &event, sizeof(event));

SE_SYSTEM_PROFILE_NAME also enabled, but no stackwalk events received in callback.

If I change EVENT_TRACE_TYPE_LOAD to EVENT_TRACE_TYPE_END, then I can get image_unload stackwalk successfully.

Really strange, anybody can help?
