Symptom
The IOS-XE packet-trace output should print additional trace information for packets punted to IOSd with IP/TCP/UDP processing information. This output can go missing sometimes without any known trigger. The only way to have get this output once it gets into this condition is to reload the router.
Conditions
This problem seems to happen after the platform conditional debugging is reset a few times with the command "clear platform condition all".
Workaround
The only known workaround at this time is to reload the device.
