Not at all the same, then. Check your BIOS for the event log of ECC errors.

Hard Hang, nothing in logs / no panics
Good Day everyone. I have this one system setup with If_bridge to filter traffic. It does work quite good. I am running FreeBSD 6.2 but as a TINYBSD Image. The one problem I have is I place the machine at the perimeter on our network with 27 seats. At that time anywhere between 15min - 24hours the entire system goes into a Hard Lock (Physical reboot needed). The thing is there is no logs or kernel panics or anything. No IRQ Conflicts exists. I am looking for any inputs or any ways to go after looking how to even diagnosed this. Here is a copy of my dmesg. Copyright (c) 1992-2007 The FreeBSD Project.

You may need the KDB_STOP_NMI option, especially if it is an SMP system. I forget if you also need to enable a sysctl on 6.x (look at sysctl -a | grep nmi for the obvious one) Am I possible looking at a hardware issue? If so what is the best way to test for it?
