Subject: [Bug testsuite/23493] Test suite makes all CPU stuck forever on kernel 4.16.16 (Fedora 27)

--- Comment #6 from agentzh <agentzh at gmail dot com> ---
The command I used to run the stap test suite was this:
```
sudo time make -j8 installcheck-parallel |& tee result.txt
```
I've attached the full `result.txt` produced that night to this PR for your
reference.
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 lines 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 force.
The virtual machine running the tests has 8GB of RAM:
```
$ free
total used free shared buff/cache available
Mem: 8143832 646244 1851164 98824 5646424 6997500
Swap: 2097148 0 2097148
```
It has 8 logical CPU cores (4 physical CPU cores with hyperthreading enabled).
Please let me know if you need any further information. Thanks!
