            Bug ID: 192906
           Summary: [dtrace] running dtest.pl causes VM to sporadically
                    reboot
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: Needs Triage
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: ngie@FreeBSD.org

Running dtest.pl causes my vanilla-ish VMware VM to sporadically reboot when
the tests are executing.

Repro:

1. Build and install a kernel with the cyclic, dtrace, opensolaris "modules" in
MODULES_OVERRIDE.
2. Run the following commands as root:

% 
% pkg install -y ksh93 nawk
% git clone https://github.com/yaneurabeya/freebsd/
% git checkout isilon-atf-integrate-dtrace
% export WITH_TESTS=yes
% make hier
% cd cddl/tests/dtrace
% make obj
% make depend
% make all
% make install
% cd /usr/tests/cddl/dtrace
% kyua test

Expected result:

The tests should complete.

Actual result:

The VM reboots. VMware Workstation notes that there was an uncaught/unhandled
hardware fault either generated by the host hardware or guest OS.
