Here's a couple of Oops's on 2.1.51. I've been having similar things
every day or two since 2.1.47.

Here's the latest:

Using `/boot/System.map' to map addresses to symbols.

Here's an older one:

Using `/boot/System.map' to map addresses to symbols.

Here's one that followed soon after the one above:

Using `/boot/System.map' to map addresses to symbols.

Let me know if there's anything you'd like me to do to try and reproduce
this. The machine is a lightly loaded server (no monitor of keyboard, just
minor file, mail, pop, and web serving with 2 client machines).
