I experienced this on several distros.
If i run
fdisk -l
i got to wait forever for it to finish, and it ends with an error (can't run it right now, will give the error later)
If i delete the devices for floppies
rm -r /dev/fd*
I can run fdisk -l without problems.

I neither know what is the source of the problem, nor how to solve it (my workaround is ok, but it is getting a bit old).

I got this as well and fixed it with adding this to /etc/rc.local

rmmod floppy

thanks.
should probably have asked that month ago ...
