It is important to be clear about what works and what doesn't:

* statically linked user programs
* statically linked user programs that use cthreads
* dynamically linked hurd servers not used in boot (e.g. try some filesytem)
* dynamically linked hurd servers used in boot
  (i.e., update everything but ext2fs.static)

Also test whether running a program via ld.so works,
i.e. /lib/ld.so.1 /bin/foo arg1 arg2

This is how exec gets run.  Try /lib/ld.so.1 /hurd/exec --help.

Chances are that one of these other permutations has the same problem,
whatever the problem is.  Then we can debug a problem case that is less
annoying to debug than the hurd boot.

As to debugging a hurd boot problem, is there a reason you haven't done
this under a sub-hurd and given more detailed information?
i.e. when the machine hangs, did one of the initial tasks die?
Can you use gdb from the main hurd and catch some exception?
