Since no /dev/acpi node, I mounted the root partition and created an acpi node /mnt/dev using mknod. Once boot, I get lot of lines in "sysctl -a | grep acpi". Since that /dev/acpi later disappear, I removed it the same way I created it by mounting the root partition.

Its mentioned in my previous mail. Its Intel P4.

BIOS seems old, but for FreeBSD 7 its not an issue, shutdown can power off. Its my second disk running FreeBSD RELENG_7 having a problem. Both versions are basically the same code, acpi code is identical, the problematic FreeBSD RELENG_7 is more evolved with various software updates.
