>Description:
I am running FreeBSD 2.2.2 with the ppp from the CDROM. User ppp runs
fine, but if I start or restart X (using startx), while ppp is running,
the system freezes after about about a second. It requires a reset to
restart the system, even ctl-alt-del has no effect. Caps-lock,
Scroll-lock and Num-lock do not result in their normal indicator lights.
If I shut down ppp with a close, followed by a quit, then all is fine,
If I use just a quit, I will still get the freeze when I start X.

It appears that X is somehow interfering with the modem port, which is 
/dev/cuaa3. I tried kernel ppp and when X comes up it kills the modem 
connection.

I have repeated the problem in both 2.2.1 and 2.2.2, on 2 machines, a
120mh Pentium and a 150mh Pentium Pro, with both XF86 3.2 and
3.3. It happens with the SVGA server for the Matrox Millennium, and the
S3V and SVGA servers for the Diamond 3D 2000. Both machines have 32megs
of memory. The Pentium has a Zoom internel modem on cuaa3, the Pro has a
US Robotics Sportster internel modem, also on cuaa3.
>How-To-Repeat:
Start user ppp, then start X, or start X, shut it down, and start X 
again. The ppp can be running in either manual or automatic mode.

 It turns out to almost certainly be hardware. I moved the modem to
 cuaa1, and the problem disappears. This was with the Diamond 3D 2000 (S3
 Virge) card. I have not yet changed the modem location in the other
 machine, with the Matrox Millennium, but since the symptoms were
 identical, moving the modem should work there too.
