I also reported this in Mar 19th with some kgdb-output:

== Hardware ==
The machine ran about 30 months without crashes, at last with 6.4-RELEASE.
The storage was on a 3ware with two attached SATA150 drives.
Then we replaced the old 3ware + 2xSATA by two onboard-attached SATA300
drives with geom mirror configuration. The new OS is 7.1-STABLE from Mar
14th, which crashed with "vm_page_insert: page already inserted" under
geom mirror status:

== What happened ==
The crash happened while cvsupping from local cvsup-mirror, hence there
was pretty much read-write i/o on the geom while having some CPU load.
After rebooting the geom-mirror was degraded and rebuilded within some
couple of hours. I didn't have had any crashes since then but don't
want to provoke this since this server is kind of "productive".
Maybe those "environmental" information does help someone to spot the
cause of this error.
