I've also attached the full /var/log/messages file content during the test = run period (also included messages right before I started running the stap test suite and right after I rebooted the machine on the next day to avoid any confusions). Some observations from the result.txt and /var/log/messages files: 1. Aug 6 23:18 I started running the test with the command `sudo time make = -j8 installcheck-parallel |& tee result.txt` (see result.txt) 2. Aug 7 00:35:57 or later: the stap test suite generates the last few line= s of output to stderr/stdout (see result.txt) 3. Aug 7 00:34:16 The kernel generated the last line of output to /var/log/messages, which was "work2 kernel: stap_e0ad497a0eaf9de8589606c16f0b585_79159: unknown parameter 'pt' ignored" After that, no kernel dmesg output until I rebooted the machine with force. 4. Aug 7 08:28:03 I got up in the morning and rebooted the machine with fo= rce. The virtual machine running the tests has 8GB of RAM: ``` $ free total used free shared buff/cache avail= able Mem: 8143832 646244 1851164 98824 5646424 699= 7500 Swap: 2097148 0 2097148 ``` It has 8 logical CPU cores (4 physical CPU cores with hyperthreading enable= d). Please let me know if you need any further information. Thanks! --=20 You are receiving this mail because: You are the assignee for the bug.
