CD-ROM tray opens on wake from suspend on Ubuntu 20.04 LTS Focal

[Veron Rado]

I'm using Ubuntu 20.04.3 LTS amd64.
Updating to kernel 5.4.0-84 seems to have been the cause.

It's a known bug in the Linux kernel

This is the upstream bug:
https://bugzilla.kernel.org/show_bug.cgi?id=213795

There's a patch there too.

I tried to set the package for this bug to 'linux' but launchpad won't let me.
It returns the error "There is 1 error in the data you entered. Please fix it and try again. A fix for this bug has already been requested for linux in Ubuntu"

This says kernel bugs should be listed under 'linux'
https://wiki.ubuntu.com/Bugs/FindRightPackage#Kernel

Edit: looks like the linux package setting went through after all!?

Edit 2: No need for logs. It's a known upstream bug see #1
Updating to 'linux-image-5.4.0-84-generic' package and dependencies seems to have been the cause.
This issue wasn't in 'linux-image-5.4.0-81-generic' package and dependencies.

[Veron Rado (junket)]

changed to 'confirmed' as per post #3

As a workaround, if you leave a disc in the drive it seems to stop the unwanted eject.

[Angus (albinard)]

I've done the upgrade to kernel 5.4.0-86, and the problem is still present. Leaving a unsed CD/DVD in the drawer and unmounting it is still an effective workaround.

[Veron Rado (junket)]

Fixed after updating to the latest kernel:
Linux 5.4.0-88-generic

Thank you :)
