OK, reassigning to the Linux kernel.

To Debian Kernel team: this bug has been revealed in D-I beta1. Any
attempt to mount an extended partition (which is done in both
mountmedia and iso-scan) loops forever and D-I appears to be
"hanged". This happens for instance each time D-I looks for missing
firmware on existing devices.

We had several bug reports about this. mountmedia has been fixed (more
with a workaround than a real fix) but iso-scan is still affected.

So, it seems that the patch described above is highly wished for
wheezy. It would be great to have it before D-I beta2, indeed.

For that reason, I set the bug's severity to critical (breaks
unrelated packages).
