Linux thinks there’s a floppy drive when there’s not. Probing slows down bootup by almost a minute.

Bug Description
Since the installation of DeviceKit-disks, the system startup blocks for almost a minute on two of my computers when udev runs /lib/udev/
Neither of the computers in question have a floppy drive, but Linux says:
[ 2.467794] Floppy drive(s): fd0 is 1.44M
I probably could workaround the problem by disabling floppy drives in BIOS settings, but one would think the OS could realize a drive doesn’t exist automatically.
% tail -n0 -F /var/log/syslog & time sudo /lib/udev/

Interestingly, lshw does not list a floppy drive at all.

Could you run sudo /lib/udev/ devkit- disks-part- id /dev/... on all your partitions and check if one of them reproduces the long hang?
It's likely that this only happens on startup, when some RAID etc. is still being assembled. Can you please attach the output of "devkit-disks --dump"?
