Could not mount iso image generated by genisoimage a second time.

No idea what's happening...
I want to burn some files to a CD. The first thing I do is to create an ISO 9660 format image file. I followed the instruction on wiki about using genisoimage. The problems is I can then mount and umount it for the first time, but on my second mount try using the same command:

sudo mount -t iso9660 -o ro,loop=/dev/loop0 img.iso /mnt

no error shows up but there is nothing on /mnt folder(on the first try everything's fine). I also noticed that every time I try to mount it after the second time, there's a "loop" device showing on the dolphin file manager(using KDE).
I tried some other .iso files downloaded from elsewhere, mount and umount, and every time it worked.

So basically what's happening here? How can I make my own iso file behave just like the others.

EDIT:Just found out other .iso files not always work neither.

Re: Could not mount iso image generated by genisoimage a second time.

I've noticed this the other day too.
The iso is pretty old and it used to mount as expected, now it works ~50% of the time.

I'm using a 32-bit Arch with [testing] repos enabled.
