However, while testing my modification, the following kernel message occurs: xl1: watchdog timeout xl1: link state changed to DOWN xl1: link state changed to UP The thing is, that this happens AFTER the whole experiment has been successfully conducted. Any ideas what might be the reason for this to happen? The code I've written is not very time consuming, and it does not "lock" the execution either. BR, Per H
