Hi,

There is a bug when cups is starting which I encounter only on one spezific hardware.
When cups is starting all my devices on the PS/2 port stop working.
When this is done on system startup no mouse or keyboard input is recognized anymore.
When cups is started via '/etc/init.d/cups start', the last key typed (\n) is repeated enlessly.

This happens when 'modprobe -q -b parport_pc' is called in the init script. By setting $LOAD_LP_MODULE to "no" in /etc/default/cups the problem can be bypassed for me, but I think it would be better to find the reason anyway since there may be some others that encounter the problem. It was not easy for me to track it down to cups since there is no obvious relation to a keyboard or mouse.

In the past year the problem showed up from time to time, letting the PS/2 work some times, than occasionally  not working which made it quite difficult to track the problem. Witrh newer kernels I can nearly 100% reproduce the problem on Debian 6. It is also seen on an aptosid 2011-02 installation with latest kernels in 32bit environment.
I currently have these two installations to reproduce the problem and run test if it needed.

Greetings,
Florian
