I am on Fedora 18 VM (virtualbox running on OS X El Capitan host), Fedora kernel version - 3.6.10-4.fc18.x86_64. The VM freezes when I execute the below shown dtrace script

/* syscall.d */
syscall:::entry
/pid == 2348/
{
printf("%s %s %s %s", probeprov, probemod, probefunc, probename)
}

Attaching the screenshot which show the point at which the system freezes.

The script runs successfully on Fedora 18 kernel version 3.11.10-100.fc18.x86_64
