i8042.c: no controller found


Hi,
I have installed debian 6.0.4 64bit on axiomtek capa830 successfully, but when i boot it this error appears on the screen and the system won't boot:

[ 1.127112] i8042.c: No controller found.
Loading please wait...
INIT: version 2.88 booting
Using makefile-style concurrent boot in runlevel S.
Starting the hotplug events dispatcher: udevd.
Synthesizing the initial hotplug events...done.
waiting for /dev to be fully populated.

The i8042 was the chip on the old IBM pc that took care of the keyboard interface. Because the capa830 is an embedded board, there is a good chance that there is no ps2 interface for the keyboard anymore. Hence the message that no device/controller has been found.

Cheers

So, What's the solution to this matter? is there a way to remove this message? This is an embedded system and it should start up automatically and this system doesn't!

To get rid of the message you have to remove support for the controller in your .config file.
I'm not sure if the missing controller is the reason that your system isn't starting correctly.
The message you posted shows that the kernel started right and started the init process. So if there's something that keeps the system from starting correctly it is somewhere in the init process.
So could you show us how far the system gets in the boot process, before you concluded it was not starting correctly?

Cheers
