Distribution: Gentoo Hardware Environment: Toshiba Tecra S1 (CD drive: hdc: UJDA740 DVD/CDRW, ATAPI CD/DVD-ROM drive), using kernel ide (atapi) support compiled as modules. Software Environment: Gentoo kernel 2.6.10-r7, KDE 3.3 and 3.4 beta2, cdrecord, cdrdao, k3b. Problem Description: Attempting cd writer detection using cdrecord, cdrdao form shell and running k3b and k3bsetup (in KDE) freezes the kernel. This happens with/without cd in drive. Hard reboot required. No messages in logs. The following modules are loaded: isofs 31544 0 zlib_inflate 17280 1 isofs pktcdvd 26428 0 ide_cd 36868 0 Steps to reproduce: Run the above mentioned programs.
This is a copy of a bug I reported to the Debian BTS. I have pasted the debian bug further down. I have demonstrated this bug with 2.6.10 and 2.6.11.7, both debian and official kernel versions. I have tested two CD/DVD writing systems; growisofs and cdrecord. The problem occurs with both. K3b is a front end for cdrecord and growisofs. I am using NEC ND3500 DVD/CD writer on a VIA KM400 chipset. Date: Sun, 27 Mar 2005 21:00:39 +0100 Package: kernel-image-2.6.10-1-k7 Version: 2.6.10-6 Severity: important Repeatability: always Problem occurs with 2.6.9?: Never Action: Attempt to write CD or DVD using cdrecord or growisofs. Symptom: Waits to write media for between 40-80 seconds. System then becomes catatonic/ totally unresponsive. Requires power removal or hit reset button. No data written to media. Media can then be used after reboot to 2.6.9 kernel. Typical command invocation leading to problem: nick@d:/mnt/dynamic/isos$ cdrecord -dev0,0,0 SimplyMEPIS-3.3.iso Kernel boot parameters: hdc=ide-scsi nick@d:~$ cdrecord -version Cdrecord-Clone 2.01.01a01 (i686-pc-linux-gnu) Copyright (C) 1995-2004 J
Is this problem still present in a vanilla 2.6.13-rc6 ftp.kernel.org kernel?
I've totally forgotten about this one. Did not use k3b or any cdrw authoring tools from the day this bug was submitted until a complete and fresh system reinstall 2 months ago (using the old kernel config though). Now running Gentoo kernel 2.6.12-r7 (gentoo-sources). cdrecord/cdrdao/k3b all work correctly - no crashes. I have burnt several CDs successfully. Not sure where or when the bug was resolved. Sorry.
