Subject: USB Keyboard

I have multiple AMD 64-bit servers in several configurations,
with several different motherboards, which fail to recognize
a USB keyboard when booted from a "stock" Linux kernel.
They only work with a RedHat kernel! I have removed all but
one CPU from one in an attempt to find the problem.

The drivers:
 	uhci_hcd      34064  0
 	ehci_hcd      34056  0

install fine, but remain unused. They don't generate any interrupts!
I even installed dm_mod (after this snapshot), thinking maybe it
would fix it. Anyway, the machines can't be accessed without a keyboard
because they don't have anything but USB. They are not on a network
either, which makes troubleshooting without a keyboard a bitch. There
apparently is a keyboard controller (which gets one interrupt), but
it is not connected to a keyboard socket.

I have tried the following stock kernels. Manufacturing and the
customer "requires" Linux version 2.6.N

linux-2.6.8 linux-2.6.9 linux-2.6.10 linux-2.6.11
linux-2.6.11.9 linux-2.6.12 linux-2.6.12.5 linux-2.6.13
linux-2.6.13.4 linux-2.6.15.4 linux-2.6.16.24 linux-2.6.16.4
linux-2.6.19

I have tried various games such as "pci=routeirq." Nothing
works! Does anybody know how RedHat gets the USB keyboard to
be recognized?

Cheers,
