As reported in this list by several people, you may be seeing that your PS/2 mouse is not detected after the recent ACPI update. This seems to be caused by ACPI in some BIOS assigns IRQ 12 (mouse interrupt) to both the PS/2 mouse device node and the system reserved resource node. To see if this is to be your case, put the following line in /boot/device.hints and reboot. debug.acpi.disable="sysresource" If this brings your mouse back, I recommend you to keep that line there until the proper fix is committed. If it doesn't solve the problem, there must be other causes ;-( You had better contact the FreeBSD ACPI developers ([EMAIL PROTECTED]) ML. Kazu PS: I am going to commit some update to the psm driver shortly. But, that alone won't fix the problem. Sorry...
