Bug description:
  Issue found on Power9 node baltar with B-5.3
  (5.3.0-41.33~18.04.1-generic)

   # selftests: benchmarks: futex_bench
   # test: futex_bench
   # tags: git_version:unknown
   # time = 52.042224
   #
   not ok 5 selftests: benchmarks: futex_bench # TIMEOUT

  
   # selftests: dscr: dscr_sysfs_test
   # test: dscr_sysfs_test
   # tags: git_version:unknown
   #
   not ok 6 selftests: dscr: dscr_sysfs_test # TIMEOUT

  Need to check if this has something to do with the timeout setting
  like in bug 1864626
