The oops quickly disappears because other problems arising from it pop up. The machine crashes and no logs are logged. I try to make foto or try to log to the serial console. At the moment I only see that there is xfrm_???? stuff in the call trace as xfrm_lookup, xfrm_route_????, and it is while routing a packet. With later kernels (4.18.5) the machine seems to crash without a call trace on console. Regards, -- Wolfgang Walter Studentenwerk München Anstalt des öffentlichen Rechts
