-current silent lockups

I would suggest you do some basic investigation, and start by running the
dell diagnostics.
Your post doesn't say how you have FreeBSD configured to run at boot, what
applications are running? Are you running it just as a text console, or
running X?
If diagnostics doesn't show any issues, try simplifying your run-time
environment, and run only a text mode console if you can.
You might also want to try other OS's that you can load and run from CD to
see if any lockups occur under those OS's.
