We're running FreeBSD current on a dual pentium 200. At
least three times now the machine has crashed with the error
message below. It isn't actually dead. The daemons that
don't need the file system still live on for a while. This
is the message faithfully copied off the console:
---- Error Message Begins ----

---- Error Message Ends ----
I'm not sure exactly which 'current' version we have, though
it is probably less than a week older than the compile date.
Here's the top of dmesg:
