    Hello!

    I have all the data you asked for:

    1. # cat 0u > /tmp/0u.mon.out
    2. The kernel log file.

    Also 3.
    # date; cat 0u > /tmp/0u_after_disconnect_usb.mon.out
    Tue Mar 30 08:50:45 EDT 2010

    Here, I ran this, disconnected the mouse and re-connected it.

    All files are here:

    http://home.comcast.net/~jpiszcz/20100330/kern.log.bz2

    Hopefully something can be found!

    It has happened again, in addition, this is a LONG outstanding bug since
    2006 or 2007, see below research:

    Sometimes the screen just freezes and the cursor will not move, and nothing responds at all. The only way (I have found so far) is to hold down the power button until the whole laptop powers off.

    Hello. This bug is *serious* because it happens with all nforce 430 chipsets.
    The problem seems to be with that specifc chipset.

    This bug is a duplicate of:
