Hi!

I have encountered a slightly annoying problem. When using my USB 
keyboard
with a SMP enabled kernel it simply won't work and I have to plug my 
old PS2
keyboard back in and reboot to get a working keyboard. With a UP 
kernel the
USB keyboard works as it should.

Any ideas?
This could be related to the following patch:

http://www.dragonflybsd.org/cvsweb/src/sys/bus/usb/usb.c?rev=1.49&content-type=text/x-cvsweb-markup

Please try to set the following tunable at boot-time:

  hw.usb.hack_defer_exploration=0
