[Bug 2042529] [NEW] Wrongly ignores drives without reported ID_ATA_FEATURE_SETs

Public bug reported:

I hope I am at the right place for this problem :)

I am using 3 hard drives in a ZFS pool on an Ubuntu Server 22.04.3 LTS.
All of these hard drives support spindown and APM via hdparm and even the manual "hdparm -B XX -S XX" command works just fine.
However, when using /etc/hdparm.conf none of these drives are configured on startup.

I traced the error back to the "hdparm_try_apm" function in "/usr/lib/hdparm/hdparm-functions", which checks via "udevadm" for the "ID_ATA_FEATURE_SET_APM" feature set. Unfortunately, none of my drives report this feature set via udevadm.
In fact, they don't report any feature sets via udevadm.

If I simply override this check, the script executes all the commands
properly, however, then it also tries to set the default APM value (254)
for my, actually unsupported, SSD.


Same problem, other guy: https://askubuntu.com/questions/1488005/spin-down-disks-using-configuration-persistent-across-reboots

Aside from the serial numbers, here is the complete output of one of my
drives, the other two have a similar output:
