Problem with de4x5 on Alpha?

[Nathan Poznick]

I've been trying to get 2.6.0-test[6|7] to boot on my AS2100 (Sable),
and have run into a problem.  If I disable networking, I can get the
machine to boot.  However if the rc script to start networking runs, the
machine hangs on it.  It's using the de4x5 driver for the NICs, but only
one interface out of the 5 possible is ever brought up.  I've only got a
serial console on the thing, so I don't know if anything gets printed to
the screen when this happens to indicate something.  However, when it
hangs I've done an Alt-SysRq-t to dump a trace, and then run the trace
through ksymoops to try and get some idea of what's happening.  Below
are three traces from when it hangs;  the first two are from booting
with smp enabled, and the third one is from when I booted with 'nosmp'.
Is there any other information I can collect to help debug this?
(Everything works fine with 2.4.21)
