With these last two commits I can boot my laptop both with and w/o ACPI (which I could do before) and with ACPI enabled but with it intentionally failing to probe (which I had not tested before). If you boot with ACPI enabled but have 'bus' set in acpi_disable then you will have succesfully blown your foot off. If someone wants to add smarts to legacy_probe() so that it handles that case cleanly (I'm not sure how it would) then you can avoid that form of foot shooting. However, acpi_avoid/acpi_disable should only be used for debugging, so if you manage to blow your foot off in that manner you are on your own. :) -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
