@Chase Douglas,

You are right, if the stop udev command is put into /etc/rc.local my usb
keyboard and mouse are not recognized at startup. However if I do not
have the stop udev command in /etc/rc.local and only run the stop
command after booting up and logging in with the usb keyboard and mouse
plugged in I get to keep the mouse and keyboard and still reduce the
load. Of course, it wont recognize other usb changes subsequently. I
understand this is a hack, but if I do not stop udev then I run out of
battery power pretty quickly and my laptop heats up very fast.

One point though: this was not an issue with 9.04, because I never
experienced this problem there. I did not try 9.10 so I cannot say. So
this, to me, indicates that it might not be a hardware problem because
the Optiarc DVD  drive was working fine in 9.04, unless the drivers have
changed with 10.04 and that is causing the excessive load.
