Mechanical HDDs may not spin-down properly on shutdown

There might be a regression introduced with 6.6.0-rc4 which got also backported to 6.1.59 and 6.5.8 Kernels. There is a discussion with the author of the offending patch ongoing here .

In Testing, there was this issue with spinning disks not spinning down. Some patch was made there but only few people reported it was fixed. I am sure this was fixed but I can not find it there?

scsi: sd: Introduce manage_shutdown device flag

commit 24eca2dce0f8d19db808c972b0281298d0bafe99 upstream.

I reckon that meant: “fixed”, but I feel noobish here…

Why did you define these udev rules in the first place? Were you on Testing branch then?
