Today, I did some testing about these often reported issues of D-I "hanging", most often when detecting network hardware or when mounting ISO images.
These issue is a kernel issue. It is being dealt with in #684293. A workaround has been committed and uploaded in mountmedia. It is confirmed working by my tests. Another workaround for iso-scan has been sent in #684293 (when I sent it, I forgot that this was the bug that had been reassigned to the kernel, sorry). It is also confirmed as working but I think it is quite ugly (blame my bad shell programming skills). The bug has been tagged pending by the kernel maintainers, so I guess that a kernel patch is on its way. If a new kernel with that patch reaches wheezy, then we don't need the workarounds anymore: - no need to commit one for iso-scan - need to revert the one in mountmedia --
