Thanks for the quick answer. Glad to see it is already known and almost fixed. I'll rather wait for 56 (to get the correct patch dependency merged) and remove 55 kernel image from /boot in the meantime. Glas my headless NAS has a fixed address because it is more tricky to get back in order and I switched it to 55 already. Thanks for the support, -- eric
