This is from a soft-updates -current kernel from August 26. All
filesystems were mounted with soft updates. The system that crashed
was doing NFS server activity at the time. A remote machine was
building a port in a directory mounted (nfsv2) from the server that
crashed. I have the -g kernel and core dump in case anybody is
interested.
Also, we still seem to have the bug in which fsck turns off the
soft-updates bit when it recovers the FS (root in this case).
