From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030206 Description of problem: When using xcdroast to try and burn a CD, the burn fails for the following error: "Input/output error. send opc: scsi sendcmd: no error" Version-Release number of selected component (if applicable): cdrecord-2.0-4 How reproducible: Always Steps to Reproduce: 1. Start xcdroast, select files to be burned, etc. 2. Push "Master & Write on the fly" button Actual Results: Got a SCSI bus reset error, no burned CD. Expected Results: cdrecord should begin burning the CD Additional info: This install of phoebe was an upgrade from a default RH 8.0 install with all errata applied. The media, files selected for backup, CDROM, and everything worked just fine under 8.0.

Did some more research and found that this bug is related to the kernel and has already been reported as #84160. I added my info there since I figured this one would be closed.
I can concur that I have been having various and repeatable problems when _trying to burn_ a CD. I use either Xcdroast, Gtoaster or cdrecord from the console. I have "successfully" burnt the 3 ISO images of Phoebe 3 (RH 8.0.9.4) but I have not installed it _pending_ the ability to back up my stuff to CD (which I seem to be unsuccessful in doing, at present). Currently, the system is still Phoebe 2 (RH 8.0.9.3) with the latest rawhide packages installed (Feb 20), CPU AMD Athlon Thunderbird 1.0G. The following kernel pagkages are installed: ]$ rpm -q -a | grep kernel kernel-doc-2.4.20-2.50 kernel-2.4.20-2.51 kernel-utils-2.4-8.29 kernel-source-2.4.20-2.50 ... as of this writing ...(Feb. 22nd -00h:52 EST)

By editing '/etc/modules.conf' and adding the following line: options ide-cd dma=1 I am now able to successfully burn/erase CDRW disks without the reset errors or timeouts near the end of 'fixating'. This is with Phoebe 3rd beta/ RH 8.0.94, with these kernels in use: kernel-2.4.20-2.48 (default) kernel-2.4.20-2.54 (from rawhide) IMVHO, turning *off* DMA by default, probably has been the main contributor of my problems with CD's. Magicdev had been removed, as per advice on the Phoebe mailing list, but until I amended my modules.conf as above, I still had consistent failures.
Changed to 'CLOSED' state since 'RESOLVED' has been deprecated.
