Input server crash

input_server does crash when opening the AT keyboard device failes.

That opening failed is correct because UBS drivers and usb_hid disables the BIOS legacy PS2 emulation.

Resolution: fixed
Status: newclosed

Fixed in hrev18694. The keyboard device add-on did not expect scancodes greater than 255, and crashed the server when they finally arrived (scancode is of type uint32).
