Well, I'll stop my requests to the drivers output immediatly. The problem is, that I only get the errors on one machine. Others (with less memory) don't react this way. It will take some time to include the patch and inform about the output. I have to reboot the machine after installing the patch and the new kernel build. This can only happen in certain time windows. Is it neccessary to wait until the error occurs or do you only want some outputs?
