https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267028 --- Comment #84 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to George Mitchell from comment #83) I found the following text on https://cateee.net/lkddb/web-lkddb/ACPI_WMI.html : QUOTE ACPI-WMI is a proprietary extension to ACPI to expose parts of the ACPI firmware to userspace - this is done through various vendor defined methods and data blocks in a PNP0C14 device, which are then made available for userspace to call. The implementation of this in Linux currently only exposes this to other kernel space drivers. This driver is a required dependency to build the firmware specific drivers needed on many machines, including Acer and HP laptops. END QUOTE So, I expect that if acpi_wmi.ko is being loaded by FreeBSD, it may well be a requirement for that machine to boot and/or operate via ACPI. But I'm not familiar with the details. -- You are receiving this mail because: You are on the CC list for the bug. You are the assignee for the bug.help
