I'm running 1.4.2 on a Dell Inspiron 7500.  I'm having problems with
keyup events being lost.  The result is from time to time, the machine
acts like a key is stuck down.  When this happens, I log in over the
network and kill X to unstick it.

Any suggestion on how to fix this?

/usr/X11R6/lib/X11/xdm/Xservers  has
:0 local /usr/X11R6/bin/X :0 vt05


/etc/ttys has
console "/usr/libexec/getty Pc"         pc3     off secure
ttyE0   "/usr/libexec/getty Pc"         vt220   on secure
ttyE1   "/usr/libexec/getty Pc"         vt220   on secure
ttyE2   "/usr/libexec/getty Pc"         vt220   on secure
ttyE3   "/usr/libexec/getty Pc"         vt220   on secure
[plus the serial port and the network ports]

/etc/wscons.conf has
#screen 0       -       vt100
screen  1       -       vt100
screen  2       -       vt100
screen  3       -       vt100
screen  4       -       -


I'm at a loss.
