Hello

I migrate from OBSD 3.1 to OBSD 3.2

On my server - I use isakmpd, pf and remote dialup based on pppd ( 4 incoming line).

isakmpd and pf work well, but remote dialup dont work - it crash system

after crash I look screen:

login: uvm_fault (0xd69905d0, 0x0, 0, 1) -> e kernel: page fault trap, code=0
stopped at _sys_fchmod +0x72:testb $0x1, 0x3c(%eax) ddb>

In my kernel I increment next options:

pseudo-device   sl      10      # CSLIP
pseudo-device   ppp     10      # PPP
pseudo-device   tun     10
