Description Alan Robertson 2020-02-23 14:34:51 UTC 
DVD drive is detected with kernel 5.5.5

DVD drive is NOT detected with kernel 5.6 rc1 and 5.6 rc2

Drive is SATA

Also tried Bluray drive - same result

Tried this with the same hardware with different kernels on Mint 19.

Additionally tried this with another different computer running Fedora 31 - same result with kernel 5.6 rc1 and 5.6 rc2

Something has definitely changed within the kernel which is no longer detecting optical drives.

I'm aware the floppy is being retired but it's a little too soon for optical media - I still have a lot of older backups on DVD.

Could you please restore the optical drive detection.

Still problematic with 5.6 rc3

Manjaro users are also reporting this:

The system is able to see the drives:

$ inxi -d

Optical-1: /dev/sr0 vendor: HL-DT-ST model: BD-RE BH16NS40 dev-links: N/A 
Features: speed: 48 multisession: yes audio: yes dvd: yes 
rw: cd-r,cd-rw,dvd-r,dvd-ram

Optical-2: /dev/sr1 vendor: TSSTcorp model: CDDVDW SH-S223C dev-links: N/A 
Features: speed: 52 multisession: yes audio: yes dvd: yes

Reverting to kernel 5.5.5 fixes this.

On kernel 5.6rc3 I was able to play a DVD in VLC after opening the disc in MakeMKV. It is still not showing in the device notifier in Plasma, nor does K3b detect a disc in inserted.

Here are my drives:

Optical-1: /dev/sr0 vendor: PIONEER model: BD-RW BDR-209D dev-links: cdrom 
Features: speed: 125 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r 

Optical-2: /dev/sr1 vendor: ASUS model: DRW-24F1ST c dev-links: N/A 
Features: speed: 94 multisession: yes audio: yes dvd: yes rw: cd-r,cd-rw,dvd-r,dvd-ram

I can confirm that kernel 5.6 rc4 has resolved drive detection - I will try out a few disks to verify this is fully functional.
Comment 4 Josh 2020-03-02 14:57:03 UTC 
Kernel 5.6rc4 has resolved the issues I had with my optical drives as well. I have tried both video and audio discs.
