Comment 322 for bug 441835

I guess this is the same problem I have, but I'm not 100% sure. I'm on 10.10/amd64 and I (still) use my floppy drive semi-regularly because I dumpster dive and thus prepare BIOS updates for older machines. Anyway, I noticed that under my current installation, being 10.10/amd64 my floppy does not work.

I booted the machine under Windows XP Home and the floppy is readable there. The most surprising, though, is that I booted the 10.10/i386 LiveCD on the same machine and the floppy then works! All on the same machine. I can rule out hardware problems fairly certainly.

In /var/log/messages, I get the following when accessing the floppy (either by using Gnome or by manually executing "mount /dev/fd0 /mnt):
