Guest environment (single-tenant DF audit QEMU/KVM guest)
uname -a: DragonFly dfbsd 6.5-DEVELOPMENT DragonFly 6.5-DEVELOPMENT #0: Thu Jul  2 06:02:54 UTC 2026     root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC  x86_64
kernel config: X86_64_GENERIC (has `options INVARIANTS`, sys/config/X86_64_GENERIC:56 -> KKASSERT panics)
compiler: cc 8.3 [DragonFly] Release/2019-02-22
PCI devices:
  hostb0@pci0:0:0:0   class=0x060000
  isab1@pci0:0:1:0    class=0x060100
  atapci0@pci0:0:1:1  class=0x010180  Intel PIIX3 WDMA2 (IDE, not AHCI)
  none0@pci0:0:1:3    class=0x068000
  vgapci0@pci0:0:2:0  class=0x030000

  virtio_pci1@pci0:0:4:0 class=0x010000 (vtblk0)
=> NO SATA/AHCI controller (class 0x010601) present; ahci.ko exists in
   /boot/kernel but has no hardware to attach to. QEMU additionally does
   not emulate SATA port multipliers (or PM FBS), so ahci_pm.c runtime
   paths cannot be exercised on this guest.
CAM: scbus0/scbus1 from ata(4); camcontrol devlist shows the QEMU DVD-ROM.
Storage root: hammer2 on /dev/vbd0s1d (virtio).
