I've already submitted a bug for cdrdao regarding the same issue. I wasn't sure wheter I should put them both into one report or not. Sorry if this bothers someone. https://bugs.gentoo.org/show_bug.cgi?id=193603 While burning with cdrecord the HAL daemon keeps polling the drive (per default every 2 seconds) to check for media changes. HAL expects burning applications to lock the device using O_EXCL. Example: Burning with growisofs or wodim: ps -A f|grep hald 3110 ? Ss 0:00 /usr/sbin/hald --use-syslog --verbose=no 3111 ? S 0:00 \_ hald-runner 3119 ? S 0:00 \_ /usr/libexec/hald-addon-acpi 3128 ? D 0:00 \_ hald-addon-storage: no polling because /dev/hdc is locked via O_EXCL 3130 ? D 0:00 \_ hald-addon-storage: polling /dev/hdd (every 2 sec) 3132 ? S 0:00 \_ hald-addon-storage: polling /dev/sda (every 2 sec) 22801 pts/1 S+ 0:00 \_ grep --colour=auto hald With cdrecord: ps -A f|grep hald 3110 ? Ss 0:00 /usr/sbin/hald --use-syslog --verbose=no 3111 ? S 0:00 \_ hald-runner 3119 ? S 0:00 \_ /usr/libexec/hald-addon-acpi 3128 ? S 0:00 \_ hald-addon-storage: polling /dev/hdc (every 2 sec) 3130 ? S 0:00 \_ hald-addon-storage: polling /dev/hdd (every 2 sec) 3132 ? S 0:00 \_ hald-addon-storage: polling /dev/sda (every 2 sec) 17528 pts/1 S+ 0:00 \_ grep --colour=auto hald Reproducible: Always Steps to Reproduce: 1. Burn a cd with cdrecord 2. run ps -A f|grep hald 3. Actual Results: HAL keeps polling drive Expected Results: HAL stops polling because of O_EXCL I'm using x86, but also tried cdrtools-2.01.01_alpha35.

Ditto. Any reason why is this a Gentoo issue, and not an upstream one? Plus, can you reproduce it with app-cdr/cdrkit?
Hello Jakub, the Linux burning situation is slightly confusing to me - I'm not a developer if that matters - that's why I reported it to Gentoo (after all it is my distro of choice ;-)). Wrt cdrkit - as you can see in #1 I tried wodim (it's the cdrecord of cdrkit) and it works just fine (it locks the drive away from HAL, same as growisofs). Regards Sebastian
(In reply to comment #2) > Wrt cdrkit - as you can see in #1 I tried wodim (it's the cdrecord of cdrkit) > and it works just fine (it locks the drive away from HAL, same as growisofs). Well yeah, I was asking because I couldn't reproduce it with cdrkit either. Then apparently cdrtools does something wrong. I'd suggest that you stick with cdrkit and be done with it, because cdrtools upstream is uhm... well, you'll get a better idea when you read http://cdrecord.berlios.de/old/private/cdrecord.html, http://cdrecord.berlios.de/old/private/linux-dist.html and others. Marking this bug UPSTREAM, you should contact the author about this if you want to get it fixed in cdrtools.
Ok, thanks! Regards Sebastian
