Machine type is irrelevant - this has occurred since at least 4.1-Release,
and has happened on at least three completely different machines with
three different mice. They are:
1) A Compaq Presario 425 (with a 486 DX/4 upgrade processor), 16MB RAM,
stock Compaq mouse. Machine is temporarily available, running
4.2-Release GENERIC kernel. Dmesg output not avilable.
2) A Compaq Presario 4764 - P166 with 24 MB RAM and IBM mouse. Machine
ran 4-Stable, but has been taken out of FreeBSD service (runs Windows now,
no problems with the mouse there).
3) IBM Aptiva - 550 MHz Athlon with 96 MB RAM and Fellowes GelMouse (also
occurs using the stock IBM mouse). This machine is the only one in
service, but when it ran Windows 98, there were no mouse problems. Dmesg
output from this machine:

>Description:
*******
* This PR is very closely related to another PR:
*
* "Mouse driver will die if you move mouse and hold a key (e.g. ALT)"
*
* These two PR's were prepared at the same time, hence the lack of reference
* numbers.
*******
Attempting to restart moused either by a kill -HUP or by kill -TERM and
restarting manually causes the mouse to be incorrectly initialized,
resulting in completely erratic pointer movements. The driver responds to
mouse activity, but nowhere close to what it should be doing.
This has happened since 4.0-Release, as tested on the above Presario 425.
The Presario 4764 first ran 4.1-Release, if I remember correctly, and the
problem existed there as well.
>How-To-Repeat:
Unplug your mouse and reconnect it while moused is running.
A Reboot is required to get the mouse working again. Attempting to
restart the mouse driver either with a sigHUP or by killing it and
manually restarting it does not work on any of the machines and mice
tested.
