This seems to be a false failure caused by test script itself (qa-

Here, test_140_kernel_modules_not_tainted is complaining about a module
'signpost' which is a test module that was inserted by an unrelated test
case (test_072_strict_devmem) which ran and failed earlier in this run
(see bug 1760649).  The fault is that test_072_strict_devmem fails to
remove its 'signpost' test module at line 768 if that assert at line 766

@Po-Hsu, could you take a look at fixing test_072_strict_devmem so that
it removes 'signpost' regardless of success or failure?
