      Description

      Since r60808/r60809 when test_interthread_messages was skipped, the sysparams test crashes the kernel due to a NULL pointer.
      Assigning to you Jim, since you're the author of that revision. However if you don't have a solution in the short term, maybe we should just skip tests accordingly.
      Looks pretty simple though.
