[Bug 517216] Re: excessive udev activity during dvd burning
Do you also get those events in udevadm monitor --kernel --property ? If so, they come from the kernel and the mere fact that the device is written to, and it needs to be fixed there. If not, that'd confirm that they are synthesized by udev (I wouldn't know where, but let's find out).

[Bug 517216] Re: excessive udev activity during dvd burning
Ah, I just noticed that this wasn't the final lucid udev yet. In that version, we indeed didn't open the CD in exclusive mode in cdrom_id. This was fixed in http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;h=38a3cde11bc77af49a96245b8a8a0f2b583a344c thus it should be fixed in lucid final. Please yell if you can still reproduce it there (then the question in my previous comment applies).

While I'm not the bug reporter, in case it helps: In karmic, I was having what appeared to be this exact problem (errors and slow burning that could be worked around by stopping udev). A recent upgrade to lucid seems to have solved the problem for me. -- excessive udev activity during dvd burning https://bugs.launchpad.net/bugs/517216 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

FWIW, perhaps it's worth trying a workaround from http://lists.alioth.debian.org/pipermail/debburn- devel/2010-May/000784.html: udevadm control --stop-exec-queue (before writing a disc) and (to restore udev behaviour): udevadm control --start-exec-queue (I just ran into this bug while chasing my own burning issues) -- excessive udev activity during dvd burning https://bugs.launchpad.net/bugs/517216 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 517216] Re: excessive udev activity during dvd burning
confirmed identical behaviour with brasero. with the brasero run, I generated monitor output (attached). discovered from monitor log that kernel is generating lots of events as soon as burning starts. First a lot of scsi events (3-5/sec), then a burst of block events (about 200 events in about one tenth of a second!) and then again lots of scsi events KERNEL[1265369955.606570] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0 (scsi) KERNEL[1265369956.098726] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0 (scsi) KERNEL[1265369956.525988] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0 (scsi) KERNEL[1265369956.931286] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0 (scsi) KERNEL[1265369956.945761] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0 (scsi) KERNEL[1265369956.962205] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0/block/sr0 (block) KERNEL[1265369956.962288] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0/block/sr0 (block) KERNEL[1265369956.962433] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0/block/sr0 (block) KERNEL[1265369956.964279] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0/block/sr0 (block) KERNEL[1265369956.964362] change /devices/pci:00/:00:09.0/host2/target2:0:0/2:0:0:0/block/sr0 (block) -- excessive udev activity during dvd burning https://bugs.launchpad.net/bugs/517216 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
