Just like the pkey01 (bug 1849093) failure, this issue was caused by move_pages12 test (bug 1831043)
If you just run these two tests on BM.Standard2.52 with 4.15.0-1031-oracle, with move_pages12 first, this test will fail with "TBROK: Test killed by SIGBUS!"
But if you run just this test, it will pass without any issue.
