Wong My system (Debian 12) has fio 3.33. Once in a while, fio crashes while shutting down after it receives a SIGBUS on account of the filesystem going down. This causes the test to fail with: generic/019 - output mismatch (see /var/tmp/fstests/generic/019.out.bad) --- tests/generic/019.out 2024-02-28 16:20:24.130889521 -0800 +++ /var/tmp/fstests/generic/019.out.bad 2025-01-03 15:00:35.903564431 -0800 @@ -5,5 +5,6 @@ Start fio..
