The vga stuff in the call stack is very suspicious. It looks like it
crashed trying to start up the screen saver.
If you are using any dynamically loaded modules ( such as the splash
module ), make sure you have recompiled and reinstaslled them.

: Hi. Nathan Ahlstrom has been helping me try to gather up information
:to solve a problem with FreeBSD-Stable and asked me to send the following
:information to freebsd-hackers.
: The problem is that Freebsd-Stable crashes after just a few hours of
:use. No core file is generated either. The crashing occurs on two
:separate machines, one a dual-p133 and the other a 486-33. Both these
:kernels are only hours old. I have been updating the kernels daily
:in hopes of a fix.
: If any further information is needed, please let me know.
