kern/122743: [mbuf] [panic] vm_page_unwire: invalid wire count: 0

[alc at FreeBSD.org]

Synopsis: [mbuf] [panic] vm_page_unwire: invalid wire count: 0

State-Changed-From-To: open->closed
State-Changed-By: alc
State-Changed-When: Thu Aug 5 05:11:59 UTC 2010
State-Changed-Why: 
The panic reported in this PR was almost certainly a result
of overflowing the vm_page's 16-bit wire_count field.  This
field has been changed to a 32-bit quantity in all versions
of FreeBSD since 7.2.  (See r186719.)
