Description Roland Wolters 2007-10-06 12:40:49 UTC 
Description of problem:
When a Benq A122 USB keyboard is attached to the computer at startup the 
kernel hangs during boot process. The last message on the monitor is
"SMP motherboard not connected"

If I detach the keyboard the startup works as usual. I can also connect it  
afterwards without any problems. If I connect the keyboard /var/log/messages 
shows:
Oct  6 14:38:46 localhost kernel: usb 4-1.1: configuration #1 chosen from 1 
choice
Oct  6 14:38:46 localhost kernel: input: Darfon USB Combo Keyboard

Oct  6 14:38:46 localhost kernel: input,hiddev96: USB HID v1.00 Device [Darfon 
USB Combo Keyboard] on usb-0000:00:1d.7-1.1

lsusb shows:

A full "lsusb -s 004 -v" output is attached.

/var/log/messages output when the keyboard is connected

In the original bug report the first line is missing.
Comment 3 Roland Wolters 2007-10-20 22:17:55 UTC 
The problem suddenly disappeared. I guess it was an update although I'm not 
sure which it could have been.
Therefore I close the bug as "worksforme".
