Hard hangs on AMD64 with mpsafenet enabled

Hi,

    I've got a Sun V20z 2 cpu Opteron box. I experience hard hangs when
    accessing NFS simulatneously from 2 processes (tested with parallel port
    builds with /usr/ports mounted over NFS with
    nosuid,nodev,soft,bg,intr). rpc.lockd and rpc.statd are both enabled for
    NFS.

    I cannot also enter the debugger with C-M-ESC (no serial console at this
    moment, sorry). When the system is running and I try to enter the debugger
    on video console I get garbage on the screen and a reboot immediately
    after. Scary stuff. I can't play with MP watchdog now (4 CPU box arrives in
    two weeks).

    I attach kernel config and dmesg output. The only modules loaded are:
    
Id Refs Address            Size     Name
 1    5 0xffffffff80100000 4ed1b0   kernel
 2    1 0xffffffff805ee000 718      accf_data.ko
 3    1 0xffffffff805ef000 1410     accf_http.ko
 4    1 0xffffffffb480c000 1cd      blank_saver.ko

    Help please.
