Hi,

Using various sources from the past couple of weeks I get reproducible
kerben panics as follows:

While preforming a backup:

panic: pagedaemon: clean anon page without backing store?
Stopped in pagedaemon at        0xf80ca48c:     exit    []

While doing 'grep pagedaemon *' in a copy of the
current-users mailing list archive:

panic: vref used where vget required
