Re: [Bug 384579] Re: Linux thinks there’s a floppy drive when there’s not. Probing slows down bootup by almost a minute.

[Chris Anckaert]

Hello Detlef,

There is a simple fix really, the problem with some Thinkpad's is they have
legacy floppy support enabled in the bios-settings, while there is no floppy
in the machine. Just disable this in the bios, and the problem is solved
after that. The boot time will then again be normal.

Best regs,
Chris.

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/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.
