Right now I'm running 4.7-RELEASE. I've compiled GENERIC kernel with debug option. It is no longer possible to reproduce the problem as described in kern/42260 (kernel panic with core dump), right now nmachine simply reboots, usually after 1-2 minutes. I think it's still the same bug. After applying provided patch and recompiling the same GENERIC kernel, machine looks more stable, it is working without autoreboot: # uptime ; netstat -in | grep Link#2 15:28 up 15:08, 1 user, load averages: 0,20 0,14 0,11 fxp0 1500 00:08:c7:ea:90:ae 16677664 0 27185842 0 0 I know other people having the same problem (autoreboot 4.7-RELEASE when using fxp NICs), I'm going to send them this patch, I think they can check if it fixes their problems, too.
