    Yes, this helps a lot.  This is a bug that David Rhodus encountered
    a while ago...   We thought we fixed it November 13'th and 16'th.

    So the question becomes... is the kernel that crashed on you what that
    was compiled with a sys tree updated prior to November 16th?  If so,
    then simply updating your /usr/src/sys and recompiling and installing
    a new kernel ought to fix the problem.
