While booting / installing FreeBSD system on Lenovo S10-3C laptop, either (internal) keyboard doesn't work or an ACPI functions. In case if booting with default options, keyboard doesn't function (just like it doesn't exists). In case if booting without ACPI, keyboard works fine, but lack of ACPI function render the laptop as pretty much useless. Fix: The problem reported & confirmed on Linux kernel as well - please, check the following link: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/677633 Unfortunately, Linux guys didn't come back with specific description of the problem fix, but mentioned there is something specific to ACPI. How-To-Repeat: Boot FreeBSD on Lenovo S10-3C.

(In reply to Alexander from comment #0) The same issue on my Lenovo Ideapad S110 with 13.3-RELEASE. My fix (quick one, needs to be integrated somehow into proper place): #include <sys/types.h> #include <sys/cdefs.h> #include <machine/cpufunc.h> #include <fcntl.h> #define I8042_COMMAND_REG 0x64 int main() { open("/dev/io", O_WRONLY); outb(I8042_COMMAND_REG, 0xae); return 0; } Thank you (over years) for the link which has conveyed to the fix.
