Hmm, I still can not reproduce. But as a workaround, here's what you can
do for now. Instead of using trace_printk() use:


    __trace_printk(_THIS_IP_, "format", args);

This will force the snprintf into the buffer and skips the bprintk trick
to post process at read time.

I see a trace_printk() commit in trace-cmd.git. Is that related? If not, I'll work on getting a small sample of the problem.
