--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
If the system is still in DDB, can you show output from the following:

db> x/gx 0xfffffe006b2d0510

This should print the address of the first element of the page's pv list,
should be an address of the form 0xffff8.*.  Then show the dword at that

db> x/gx 0xffff8...

Then do

db> show pte <addr printed by the last command>
