We had tried to find the program triggering the bug by putting some
debug output into programs called from inittab and it seems that it
is the last step in initab (dbootstrap, the "real" installer program),
that causes the kernel to hang. You could try filling it with debug
output to find the exact point where the crash occurs.
It is btw. a real crash - if you boot with init=/bin/sh, configure the
network and manually single-step through inittab, you can see that
pinging the box works, but in the moment you start dbootstrap, there
are no replies to pings anymore, so the kernel is really dead at that
point of time.
The boot-floppies cvs tree (including dbootstrap) is available by
cvs -d :pserver:firstname.lastname@example.org:/debian-boot co boot-floppies
if you would like to try your luck.
