If you can download trace-cmd from: git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git compile it and install it, and then run: trace-cmd record -m 100000 -e all -l warn_slowpath_null:traceoff And let it run till you see that warning again, and then I can set up a place to send the trace.dat file that's created to me.
