NetBSD 1.4P (CUSTOM) #8: Fri Dec  3 11:16:25 MET 1999

With soft dependencies enabled I to run the following command:

    ( cd /usr && \
      rm -rf src obj X11R6/src pkgsrc pkgobj && \
      dd if=/dev/rsd2d bs=32k | gunzip | restore rf - )

After restoring some files the disk was 100% active, did not seek
and the machine looked dead.

A `reboot 0x100' from ddb gave `panic: lockmgr: no context'.

From the crashdump `systat buf' gives:

File System  Bufs used   %   kB in use   %  Bufsize kB   %  Util %
/usr               511  60        2622  78        3152  93      83
/                   22   2         160   4         160   4     100

Total:             533  63        2782  82        3312  98      83

The crashdump is available on request. Process stack dumps follow.
