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.
