# readelf -a -W /boot/kernel/kernel | fgrep shstrtab
  [24] .shstrtab         STRTAB          0000000000000000 7975ee 000124 00      0   0  1

And then:

# dtrace -n 'syscall:::'
dtrace: invalid probe specifier syscall:::: "/usr/lib/dtrace/psinfo.d", line 90: failed to resolve type kernel`struct thread * for identifier curthread: Module is no longer loaded
