The amd64 machine fails to power down while running: 7.2 7.3 current (as of 2023-09-20) Today (2023-09-27) I installed latest snapshot on a usb stick, same issue. The snapshot: https://cdn.openbsd.org/pub/OpenBSD/snapshots/amd64/ The install bsd.rd successfuly rebooted after pressing R+Enter (as expected). The booted up system stalled after either reboot or halt -p. It might be noted that there are a few not configured devices: dot ~$ dmesg|grep "not configured" "PNP0C14" at acpi0 not configured "PNP0C14" at acpi0 not configured "PNP0C14" at acpi0 not configured "AMD 17h/6xh IOMMU" rev 0x00 at pci0 dev 0 function 2 not configured vendor "AMD", unknown product 0x1485 (class instrumentation unknown subclass 0x00, rev 0x00) at pci5 dev 0 function 0 not configured efifb at mainbus0 not configured
