> Why would you need dmesg if you get your hw errors over the tracepoint?
Redundancy is a good thing when talking about mission critical systems. dmesg
may be feeding to a serial console to be logged and analysed on another system.
The tracepoint data goes to a process on the system experiencing the errors. If the
errors are serious (or a precursor to something serious) that process may never get
the chance to save the log.
