Guest: DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul 2 06:02:54 UTC 2026 root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64 (QEMU/KVM, single vCPU) Compiler: cc 8.3 [DragonFly] Release/2019-02-22 Guest /usr/src/sys/dev/netif/ath/ath_hal/ar5212/ar2317.c md5 = 5c1f04b81ecd19f93eb563347ee000fd (== audit tree copy) No ath(4) hardware on the guest (no /dev/ath*) -- as with the family twins (DF-4619/4620/4622, DF-4648/4649/4650, DF-4660/4661/4662), the defect is verified by compiling the VERBATIM kernel function bodies (anchor-extracted from the guest's own /usr/src) against a faithful struct layout; no kernel code was modified, no kernel rebuild needed. HALASSERT is a no-op in this release kernel (AH_ASSERT undefined, ah_internal.h:665-676) exactly as in GENERIC. Work dir: /root/df2317. No /usr/src changes (copies only). No panic.
