OK I also found that the steps mentioned in my previous post were temporary, meaning the changes I made did not persist after a couple of reboots and resumes from suspend.
The good news is now I now have the exact output that occurs after stopping /dev/sr0, it is as follows # hal-disable-polling --device /dev/sr0 Polling for drive /dev/sr0 have been disabled. The fdi file written was /etc/hal/fdi/information/media-check-disable-storage_model_Optiarc_DVD_RW_AD_7560S.fdi Clearly this shows that the Optiarc drive is involved, so it is a genuine problem for those of us that have Optiarc drives. BTW, stopping polling reduced my load in a matter of seconds from close to 100% to close to 0%. Please keep this bug active (and critical) till it is fixed by someone in the know. Thanks. -- CD-ROM polling on some Optiarc drives causes high CPU usage https://bugs.launchpad.net/bugs/379780 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
