Here is what a successful CD-R burn looks like on thor. This was done after experiencing 2 system crashes attempting to burn DVD-R media from a no-name manufacturer (GQ -- "Great Quality" from Fry's Electronics) and a 3rd system crash attempting to burn DVD+R media from Memorex. The only supported modes from the GQ media were "PACKET SAO", thus the -sao in the command line above.

[root@thor akahlich]# I have tried to burn yet another of the GQ (Fry's generic) DVD-R's and it has crashed thor for a 4th time. This time I ran the session from an ssh console remotely so that the console output would not disappear when the machine crashes.

Performing OPC... ------------------------------------------ The last line from thor is the blank line below 'Performing OPC...'. I don't know if this is a generic cdrecord problem -- the reason I say this is I remember having this problem a couple of years ago on a completely different computer with a different Linux distribution. There I had some marginal CD's due to the way they were stored, and about one out of 4 CD's would crash that machine at precisely the same point in the record process. Can you burn with growisofs instead of cdrecord?? This request was evaluated by Red Hat Engineering for inclusion in a Red Hat Enterprise Linux maintenance release. As this bug has been in NEEDINFO for an extended period of time we are going to close this bug due to inactivity. If you would like to persue this matter feel free to reopen this bug and attach the needed information. With the goal of minimizing risk of change for deployed systems, and in response to customer and partner requirements, Red Hat takes a conservative approach when evaluating enhancements for inclusion in maintenance updates for currently deployed products. The primary objectives of update releases are to enable new hardware platform support and to resolve critical defects. However, Red Hat will further review this request for potential inclusion in future major releases of Red Hat Enterprise Linux. |
Description of problem: cdrecord failure in OPC causes system crash Version-Release number of selected component (if applicable): cdrecord-2.01.1-5 How reproducible: Try to record a DVD where OPC fails and the system becomes non-responsive, requiring holding the power button for 4 seconds to restart. Steps to Reproduce: 1. Open DVD writer tray, place blank but defective DVD-R in tray, leave open. 2. Make a .iso file using: mkisofs -l -r -o valid_iso_file.iso some_directory where valid_iso_file.iso is not in some_directory or any sub-tree of it. 3. As super-user, enter cdrecord -v -eject -sao speed=16 dev=4,0,0 valid_iso_file.iso 4. System crashes with "...OPC" on last line. Additional info: My kernel boot line looks like: kernel /vmlinuz-2.6.9-34.0.2.EL ro root=/dev/VolGroup00/LogVol00 hda=ide-scsi console=ttyS0 rhgb quiet and yes, I added the hda=ide-scsi to the boot line myself. Please let me know if this will cause problems and recommend how I should configure the driver software instead. There are no other devices on the IDE ribbon cable with the DVD writer drive. The only other drive in the system is the SATA hard drive containing the boot, swap and filesystem root ('/') partitions.
