Could be various reasons, hardware or software. Ideally leave the serial console connected so you capture any output before the system enters ddb (if this is not possible then at least do "show panic"). Also get ps, trace, and "show registers" might be useful. > I am just wondering before I invest a lot of time/effort in trying to fix the > system. It is probably worth updating to 5.1 before spending time on it, in case it's a kernel bug which has since been fixed.
Re: ddb prompt on formerly stable system (4.9)
When you get the ddb run ps and trace. Also include dmesg output.

ddb prompt on formerly stable system (4.9)
Hello: If this is a really stupid question, please be gentle. So, I have had a machine with 4.9 running for a year or so.B Except for some minor tweaking (changes to pf.conf and the like), nothing has been installed and there have been no major changes to it. This morning (before I came to work), I noticed the system wasn't responding.B I went to the basement, got out my really old laptop as a serial console, and noticed the system was giving a "ddb>" prompt. Just for kicks, I reboo ted, and at some point after the networking comes up, the system paniced and gave the "ddb>" prompt again (i can't recall the error - still at work).B I have been doing some googling in my free time, but could not find anything to help me with the question below. Anyway, my stupid question:B This is almost certainly a hardware problem, right?B A dying disk, or something like that? I am just wondering before I invest a lot of time/effort in trying to fix the system. Thanks bye - ted
