On a not very current machine:

FreeBSD toots.physik.rwth-aachen.de 2.2-970225-GAMMA FreeBSD 2.2-970225-GAMMA #0: Wed Apr  2 16:57:52 CEST 1997     kuku@toots.physik.rwth-aachen.de:/usr/src/sys/compile/TOOTS  i386

I got the following crash today after 29 days of uptime:

Apr 29 16:12:39 toots /kernel: 
Apr 29 16:12:39 toots /kernel: Fatal trap 1: privileged instruction fault while in kernel mode

Apr 29 16:12:40 toots /kernel: syncing disks... 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6 6

from kernel symbol table:
f019f7cc t _vm_map_entry_delete
f019f820 T _vm_map_delete   <<<<<<<<< ip = f019f837
f019f9a8 T _vm_map_remove
f019fa5c T _vm_map_check_protection

Were there fixes or changes in 2.2.1R or 3.0-current in that area,
that would make it necessary upgrading the machine?
