I could be wrong about that.  I mainly looked at the CVS logs.

I did boil the problem down a bit more...   I think the hard
hang happens when you run the first program linked with "pthreads"
(i.e. /usr/sbin/named).   IF you don't run named, I bet the 
system will boot to multiuser OK.

I just did the following test:
[1] boot to single user
[2] "mount -u /" and "mount -r /usr"
[3] run "ifconfig" and "route add default" to bring up network
[4] run "/usr/sbin/named" --- system hard hangs here, won't break to
    DDB and requires a power cycle to recover.

I'm wondering if your patch failed to setup some register that
is required for threaded apps?   I don't know the alpha architecture,
so I'm not clear on what to do.   Maybe someone here who knows
alpha can look?   I can easily test any proposed fixes.

My userland is a 4.0 one, in case that matters.
