Random disfunktion of the keyboard

Hi, my problem is, that my keyboard an touchpad randomly don’t work after grub. I’m not able to push any button after grub.
I’m using OpenSuse 11.0 on an FSC Amilo L7300.
I only have this problems with OpenSuse. Checking dmesg, systemlog and bootlog don’t give me any info. Does anyone has an idea where to search for the problem?
It seems as if keyboard and touchpad aren’t connected.
Thanks for your help.:slight_smile:
