From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031014 Description of problem: When using cdrecord as a normal user I see the following warning messages: > cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler > cdrecord: Permission denied. WARNING: Cannot set priority using setpriority(). > cdrecord: WARNING: This causes a high risk for buffer underruns. I changed /usr/bin/cdrecord to suid root, as suggested in the man page: chown root /usr/bin/cdrecord chmod 4711 /usr/bin/cdrecord ... however this didn't help. There don't seem to be any actually problems burning CD's as a normal user, just the warning messages. These warnings are not present when using cdrecord as the root user. Version-Release number of selected component (if applicable): cdrecord-2.01-0.a19.1 How reproducible: Always Steps to Reproduce: 1. as normal user: cdrecord -v -dao -pad -eject <image.iso> 2. 3. Actual Results: CD burned fine, but warning messages are displayed Expected Results: no warnings Additional info:
just warnings that it cannot get into the realtime scheduler... please report this upstream to the author of cdrecord
