i doubt kbdmux(4) is your problem. according to the dmesg you have 
posted you dont seem to use/load kbdmux(4) driver. it is highly unlikely 
that my changes in /sys/dev/kbd/ cause this. kbdmux(4) is not default 
keyboard and, at this point, one must configure/load it by hand. my 
guess would be that you, perhaps, have some sort of interrupt routing 
problem or something like it.
