[*] spawning 8 concurrent I/O threads on /dev/md0
[+] all threads completed; device path returned cleanly
RUN_EXIT=0
--- guest status after run: up (no panic) ---
NOTE: /dev/md0 is "Malloc disk" (mdcreate_malloc, sys/dev/disk/md/md.c:530),
so mdstrategy (md.c:191) routes to mdstrategy_malloc (the CORRECT variant that
refreshes bp at :239) and NEVER enters mdstrategy_preload (the buggy variant
at :345 that never refreshes bp). No preload md device exists on this guest;
mdcreate_preload (:437) is called only at boot from loader-preloaded images
(md_drvinit:501, preload_search_next_name:513) and no image is preloaded here.
=> The buggy path is dead code at runtime on this guest (LATENT).
