Well, I'll send it to you or anyone else if you can provide me with the link
of what you want.
Only thing I ask is that an official Mesa 4.0.4 FSBD port makes it into the
5.0 release as well as the next 4.x release. ;o)

The incompleteness is because you didn't do a backtrace in ddb at
the time of the crash, and only did it in gdb

Is sysinstall still supposed to copy the contents of the mfsroot-
image to /stand ? This at least results in two copies of sysinstall,
one in /stand and the other one in /usr/sbin.
