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
VM: QEMU/KVM, no GPU, no 3ware/PCI RAID controller, single vCPU-friendly minimal hardware
Kernel: X86_64_GENERIC (INVARIANTS ON, no SMAP/SMEP/KASLR)
Hardware gating:
  - twe (DF-4178/79/80): driver binds PCI 13c1:1000/1001 only; no such device => no /dev/tweN (control node would be 0600 root:operator)
  - radeon (DF-4181/82): radeon.ko requires ATI/AMD GPU; no /dev/dri in guest
Fix build: make -j6 nativekernel KERNCONF=X86_64_GENERIC with all five batch fixes applied => see fix_build.log
