Probably the message is generated by the kernel and cannot be ignored.
Try this:
% perl
use POSIX qw/:fcntl_h dup2 setsid/;
if (fork) { exit; }
setsid;
my $fd = POSIX::open "/dev/null", O_WRONLY or die "Can't open /dev/null: $!\n";
dup2 $fd, 0;
dup2 $fd, 1;
dup2 $fd, 2;
sleep 5;
system "sudo mount /dev/fd0 /mnt";
% # wait for an error within 5 seconds or so
If no error appears, I think you forgot the / on /dev/null up there :-) Make
sure to unmount the floppy afterwards.
If there is an error, it proves that it was/is a kernel message.
