Hi,

After recent changes to sys/vm/ by alc@, I'm getting panics as soon as I
start xorg-server with nvidia-driver (both 195.22 and 195.36.15):

panic: mutex page lock not owned at /home/yuri/src/FreeBSD/head/sys/vm/vm_page.c:1547

(sorry, can't get kernel to dump correctly to provide more info:
Cannot access memory at address 0xffffff007ff8ffe0
(kgdb) #0  0x0000000000000000 in ?? ()
Cannot access memory at address 0x0
)

Commenting out assert on line 1547, sys/vm/vm_page.c gets rid of panic,
but even I understand that it isn't correct at all.

Could someone please take a look at nvidia-driver kld source for
possible fix?


TIA,
Yuri
