[linux ia64] : KDB doesn't run with USB keyboard

[Sebastien Lelarge]

We are trying to use KDB-2.1-ia64 on McKinley processor. It compiles in
the kernel 2.4.17 but when we invoke KDB at the startup with the Pause
key (on an USB keyboard), we get a frozen screen and nothing is
displayed when we strike a key. We think that the problem comes from the
USB.

The USB driver is included in the kernel (not as module) and the
keyboard works at boot time. It seems that KDB doesn't have the USB
driver in his list of drivers. 

Does a patch exist to solve the problem ? Or are we condamned to modify
the code of KDB ourself ?
