This has affected 5.2-RELEASE and also affects 5.2.1-RC2. The keyboard gets disconnected after it has been reset. Workarounds (any one is sufficient): 1. add to /etc/loader.conf: hint.atkbd.0.flags="0" 2. add to /etc/loader.conf: hint.atkbd.0.flags="2" 3. compile kernel with "options KBD_RESETDELAY=1600" I haven't done a full search for the minimum required RESETDELAY. I may follow up >How-To-Repeat: Boot FreeBSD on an i386 machine with a KBPC-S2 keyboard attached. WARNING: Make sure you have a chance to shut down the machine without pressing reset, for instance, by configuring a serial console or install sudo so you can "sudo halt" from another machine in your LAN. >Fix: Consider either making hint.atkbd.0.flags="0" the default or changing the KBD_RESETDELAY default (default 200, unit ms) >Release-Note: >Audit-Trail: >Unformatted:
