Are you willing to try debugging it complicatedly?Wouldn't this be a good time to learn about mounting the file system via rump? At the very least, your whole system won't crash, and it might be easier to debug with gdb than with ddb. :)Paul and David, Sure, will take a shot at diagnosis with whatever tools and time I have. I've used gdb in some light debugging, never meddled in ddb that I'm aware. Point me to docs and/or give me a rough series of commands / objectives and I'll give it a try.
Assuming you're using a GENERIC kernel, or at least one with the necessary options...
Have a look at the rump_ffs(8) man page, and use rump_ffs to mount the suspect filesystem rather than letting mount(8) and mount_ffs(8) do it.
Good luck!BTW, I've never done this, but (famous last words) "it should work". At the very least, you should get a core dump from "the userspace server process" which can be examined with gdb.
