[Bug 379780] Re: CD-ROM polling on some Optiarc drives causes high CPU usage

[Mark Fernandes]

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.
