And that would be me.  (4.0 with a fairly recent 4.0_STABLE kernel to be 
specific, and a Samsung phone)

When I first tried to get things up and running, there were some timing 
problems in getting NetBSD to talk to the phone; i.e. the chat script 
sometimes left things in a state which didn't get me a connection.  I 
tried repeatedly running "ppp stop" and "ppp start", but after some number 
of tries this left me with a hard lockup.  Or what seemed like one at 
least, I was using X and have no idea what the console might have said.

After the chat script problems were worked out, things were fine for a 
while.  But since the connection is reset every day, I have to restart it 
regularly.  And after about a week, another hard lockup.

I have started unplugging and reattaching the phone at least once every 
2-3 days.  No problems whatsoever since, and it has been at least three or 
four weeks of uninterrupted uptime.

Same here really.  The phone is my sole net connection, and it is 
regularly up for 20+ hours at a time; that is not a problem.  Repeatedly 
bringing the connection up and down seems to be what kills things, but I 
should probably investigate some more (and try to crash things that way).
