A few questions: - the trace is taken on a ppc64 machine. Is is viewed on a ppc64 too, or on a different arch size/endianness ? - Can you provide some information about the content of the trace directory ? (files, file size) Also, trying to enable "CONFIG_LTT_DEBUG_EVENT_SIZE" might help by providing extra self-check on trace metadata consistency.
