Description of problem:
I can write a CD when I am root but it does not work when I am a regular user.
I'm using xcdroast version 0.98alpha15-1, cdrecord version 2.01.1-9.0.FC4.1 and kernel 2.6.13-1.1526_FC4smp and I have activated the non-root mode in xcdroast.
My drive is a LG DVD+RW ( model DVDRAM GSA-4163B Rev. A102 )
When I click on the "Master and write on the fly" button and I get the following error message from cdrecord ( see attachement for the full error message ):
cdrecord: Cannot allocate memory. Cannot get SCSI I/O buffer.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Open xcdroast
2. Click on "Create CD/DVD"
3. Click on "Master track"
4. add files
5. Click on "create session/image"
6. Click on "Master and write on the fly"
Actual Results: Error writing track ( see attachement for the complete error message )
Expected Results: When I am doing this log in as root, everything is working fine the track is burned on the cd.
Everything was working when I was using Fedora Core 2

"I have activated the non-root mode", what do you mean by that?
I activated the "non-root mode" in xcdroast to be able to burn cd as regular
The "on root mode" does the following command:
/bin/chown root /usr/lib/xcdroast-0.98/bin/xcdrwrap
/bin/chmod 4755 /usr/lib/xcdroast-0.98/bin/xcdrwrap
If you want to activate de non rot mode in xcdroast go in:
2. Click on the users tab
3. Click on "Change non-root configuration"
4. Click on "Activate non-root mode"
I have also discoved that cdrecord will not work if I am running it as a normal user **even if the
program is set UID to root!!
Here is a short snippet of output:
TOC Type: 1 = CD-ROM
scsibus: 1 target: 1 lun: 0
Linux sg driver version: 3.5.27
Using libscg version 'schily-0.8'.
/usr/local/bin/cdrecordlocal: Warning: using inofficial libscg transport code version (schily - Red Hat-

/usr/local/bin/cdrecordlocal: Cannot allocate memory. Cannot get SCSI I/O buffer.
If I become root, then it runs to completion.
I can't burn a CD using cdrecord or Gnomebaker unless I do it as root. This is
on FC5 by the way.
Is anybody working on this?
This report targets the FC3 or FC4 products, which have now been EOL'd.
Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?
As I have been laid off from my sysadmin job as of 11/30/2006 due to
a funding shortfall (a little over a year since this bug was first
reported), I am not in a position to submit additional information, and
have removed myself from the cc list. I hope the others involved can
I made a test on Fedora Core 6 and everything was ok!
