For those like me, who have no idea what to do with udev rules, here are
step by step intructions to fixing this problem:
hit alt+F2 for command line (or open a terminal if you prefer).
paste this command for gedit to open the rules file with root:
# gksu gedit /etc/udev/rules.d/70-persistent-cd.rules
Paste these lines at the end of the file to add the udev rule (provided by
Martin Pitt on #72):
SUBSYSTEM=="block", ENV{ID_VENDOR}=="Optiarc*", ENV{ID_MODEL}=="*AD-7640S*", \
ENV{UDISKS_DISABLE_POLLING}="1"
Save & restart udev (sudo restart udev).
That's it.
I am extremely disappointed by the way this bug was treated. The optiarc
cd-rom and dvd drives can be found on many laptops and the high cpu-
usage is a real issue. Instead of addressing this problem as a real bug
and releasing an actual solution we were presented with a lot of non-
user-level data and a problem bypass that doesn't really give an
ordinary person the ability to fix the problem.
So much for "Linux for human beings" ... (Again, Extremely disappointed)
