no uevent after ejecting CD-ROM

[Removed by request]

I'm using Ubuntu 15.10 dev with udev 219-10ubuntu1 and I'm noticing that udev rules are only executed while the system is booting. For example the file "/lib/udev/rules.d/10-test.rules" with the content "KERNEL=="sr0", RUN+="/usr/bin/touch /tmp/test.txt"" does create the file /tmp/test.txt on booting but if I'm then deleting the file and ejecting /dev/sr0 the file isn't created anymore.

Can you please run

  udevadm monitor -e --udev

then eject sr0 (in a different terminal), then copy&paste the whole output of udevadm monitor here?

Physically ejecting /dev/sr0 results in this output:

root@ubuntu:~# udevadm monitor -e --udev
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

Right, so this is (at most) the kernel's fault. I'm not sure whether ejecting a CD is supposed to trigger an uevent, but maybe not in all cases?

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1458470

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

In the past physically ejecting /dev/sr0 has worked for me. A recent apport-collect (while this report was already made) against "linux (Ubuntu)" was done here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1463627

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.1 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I'm using user-defined udev rules which I have noticed stopped working shortly before I have created this ticket. Based on these rules I have created the testcase in the startpost so yes, this was working not much time before I have created this ticket.
