I have tried this with recent 4.4.y and 4.9.y= with similar results; unfortunately, switching to a newer kernel is not easily possible on this hardware at the moment. Please let me know if the= re are any known issues or patches that I should backport. There seem to be two separate issues: 1) Building with CONFIG_DYNAMIC_FTRACE leads to a kernel panic as soon as= kernel modules are loaded (logs attached). 2) function_graph tracer does not show anything useful: the trace output looks like what was reported in [1]. Building with CONFIG_FUNCTION_GRAPH_TRACER leads to a completely empty trace_stat/function0 (except for the header); profiling is working as expected when CONFIG_FUNCTION_GRAPH_TRACER is disabled. I would be thankful for any pointers that might help me to make this work= =2E Kind regards, Matthias [1] https://www.linux-mips.org/archives/linux-mips/2014-11/msg00295.html --------------BD29AB5286C6C854E8A7FF0C Content-Type: text/x-log; name="panic-4.4.log" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="panic-4.4.log" [ 0.000000] Linux version 4.4.120 (neoraider@avalon) (gcc version 5.4.= 0 (LEDE GCC 5.4.0 r3826+66-2e26bdfeca2f) ) #0 Sun Mar 4 09:26:34 2018 [ 0.000000] bootconsole [early0] enabled [ 0.000000] CPU0 revision is: 0001974c (MIPS 74Kc) [ 0.000000] SoC: Atheros AR9344 rev 2 [ 0.000000] Determined physical RAM map: [ 0.000000] memory: 08000000 @ 00000000 (usable) [ 0.000000] Initrd not found or empty - disabling initrd [ 0.000000] No valid device tree found, continuing without [ 0.000000] Zone ranges: [ 0.000000] Normal [mem 0x0000000000000000-0x0000000007ffffff] [ 0.000000] Movable zone start for each node [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x0000000000000000-0x0000000007ffffff] [ 0.000000] Initmem setup node 0 [mem 0x0000000000000000-0x0000000007f= fffff] [ 0.000000] Primary instruction cache 64kB, VIPT, 4-way, linesize 32 b= ytes.
