5 is EIO (see /usr/include/sys/errno.h), and it comes effectively from
sys/dev/pckbport/pckbport.c:pckbport_poll_cmd1. Either you have a line
"pckbport_cmd: send error" befor that error, meaning it could not send
a command to your ps/2 mouse, or it timed out waiting for a reply from 
your mouse.

Can you test with a different mouse connected?
