I just compiled and loaded kernel 6.15.1. Up to now FPAC 4.1.4 is running fine and performing connexions with neighbour ROSE nodes. I will let it run a while before starting to apply progressively the AX25 and ROSE patches committed in kernels 15.2 to 15.10 I will start with ax25 ones and see what happens. 73 de Bernard f6bvp / ai7bg Le 16/08/2025 à 19:49, Bernard Pidoux a écrit : > Hi David, > > Actually Ubuntu stops responding without any message.
