Comment 0 for bug 1860093

Issue spotted on the following kernels:
  * linux-oracle 5.0.0-1010.15~18.04.1
  * linux-gcp 5.0.0-1029.30

The jenkins job will timeout with the 4hr threshold, however it seems that the test itself has finished in 45 minutes

This issue is preventing the report being generated. It will be a failed-to-build job on jenkins server.

This is the end of the report on jenkins server:

 [77] (instance) event trigger - test histogram modifiers [PASS]
 [78] (instance) event trigger - test multiple histogram triggers [PASS]
 [79] (instance) trace_marker trigger - test snapshot trigger [PASS]
