releng_6_2 pagefault

[Max N. Boyarov]

Hi,
I have setup RELENG_6_2 system (also check on RELENG_6).

But when packet come from net0 to net1 system do pagefault.
This is 4 core Intel Xeon. debug.mpsafenet = 0.
kernel builded with FAST_IPSEC support and isakmpd used for IKE exchange.


net image
net0 [ gif tunnel ] [ pf based router ] [ ipsec tunnel ] net1
