No, I don't.  The whole system is unstable.  E.g. ifconfig hangs at
the random time.  Wireless stops working, mouse is lagging.  Suddenly
the whole system just hangs.

yal@ replied in the private email debug.mpsafenet="0" did help him
too.

I didn't suggest to turn off mpsafenet forever and forget, I just
wanted to check my guess.  I would like to help to debug the problem
but I need some initial instructions to start.  There is a firewire
console.  What do I need to check?
