Hello, I have recently updated a machine to 7-stable. ACPI doesn't seem to work correctly on this machine. With earlier versions of FreeBSD (including the latest RELENG_6), I got this line in dmesg: ACPI disabled by blacklist. Contact your BIOS vendor. And everything was fine. The box runs perfectly well with ACPI disabled. (I can't get a BIOS update because the mainboard is too old.) When I updated to RELENG_7 a few days ago, the above line did _not_ appear anymore, and the machine didn't proceed to boot, so I had to travel to the console. :-( After disabling ACPI manually via boot.conf hint, it is up and running fine again. Now i'm wondering: Has the ACPI blacklist been removed intentionally, or is this a regression? Certainly I did not find any mentioning of it in UPDATING or anywhere else. Best regards Oliver PS: This is a Gigabyte GA-6BXD board with two Celeron-466 processors on it. Apart from not wanting ACPI it is rock- solid, and I expect it to be in production for DNS, packet filtering, mail backup and small web server for at least another 10 years. -- Oliver Fromme, secnetix GmbH & Co.
