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

[Dave Efflandt]

Dell Inspiron 8200 could not suspend/hibernate in 10.04 LTS with latest
updates and standard drivers or nvidia(96), with or without nomodeset
(would awake after 20 seconds).  Finally after installing and testing
"uswsusp" package, the console was enlightening:

end_request: I/O error, dev fd0, sector 0
Buffer I/O error on device fd0, logical block 0
Freezing of tasks failed after 20.00 seconds (1 tasks refusing to freeze):
udisks-daemon

It has hot docking drive slot (currently DVD), but BIOS shows floppy
drives "Not Installed", and removed floppy from boot order.  No other
related BIOS settings and no help.

So I commented out fd0 mount in /etc/fstab and blacklisted floppy in
/etc/modules.d/blacklist.conf, but floppy module kept showing up on
boot, and could not rmmod it (showing used by 1, but nothing else
showing it being used).

What I did not know about was "sudo update-initramfs -u".  Now floppy
module is gone and suspend works.  Success.
