Hello! we recently installed OpenBSD/amd64 on Supermicro X9DR3-F, it hangs about 1 times a day. 5.1 does not understand i350 chip, so we put external "Intel PRO/1000 MT (82574L)" nic.
we have ddb.panic=1, but no ddb appears on screen on hang. also, it says "savecore: no core dump" during boot. we tested RAM with memtest, so we do not suspect it for memory related issue. how can we diagnose those hangs ? is it ok to run 5.1 on X9DR3-F ? do I need to provide dmesg output ? any other kind of diagnostics ? Cheers, Ilya Shipitsin
