           Summary: Linux thinks there’s a floppy drive when there’s not.
                    Userland doesn’t appreciate.

Note: I’m running an Ubuntu kernel. The tree selector did not have an “Ubuntu”
or “Other” option.

Since the installation of DeviceKit-disks, the system startup blocks for almost
a minute on two of my computers when udev runs /lib/udev/devkit-disks-part-id
for fd0.

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.

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