Hfff--hard to tell. glibc won't work at all, so don't even try it.
Only one I can think of is the futex redirection being set and screwing
something up, but afaik, it is disabled by default...just a sec...yep
it is disabled.

I really don't know--do you get anything on the console? Can you
try the same kernel without fusyn patches?

For that, do:

hg clone -U http://kernel.org/hg/linux-2.6
hg update cc120a05eed4

And compile and install that kernel. If it works ok, then fusyn is
the culprit.

There I have no idea--haven't look at Ingo's patches for a long time.
