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)

Could you please try 2.6.0-test5 ? Or even better, 2.6.0-test7 with
the 2.6.0-test5 driver (revert de4x5.[ch] and the Space.c changes) ?
The usual debug informations would be helpful too...

I reverted de4x5.[ch] and Space.c to their -test5 versions, and I get
the same effect. If I disable the starting of networking, and boot, I
can then see this when I attempt to start it:
root@buddha:~# /etc/init.d/networking start
Setting up IP spoofing protection: rp_filter.
Configuring network interfaces... done.
root@buddha:~# eth1: media is 100Mb/s.
After that, it's locked up. Sometimes it prints the media notice before
it hangs, and sometimes it doesn't. I don't believe I've ever seen it
print that when I booted with nosmp (always hangs before it gets that
far.) Also, when SMP is enabled, sometimes when I do the SysRq-t I see
this right before the trace starts:
smp_call_function_on_cpu: initial timeout -- trying long wait
And then down mixed in with the trace, I get a notice from a BUG_ON() at
line 878 of arch/alpha/kernel/smp.c Decoded, it looks like this:
Kernel bug at arch/alpha/kernel/smp.c:878

This is what lspci shows. The 21040 is built into the I/O board, but is
only 10mbit so I don't use it. The 4 21142/43 entries are the ports on
a 4-port DE500-BA card. I'm using the first port on that card for my
connection. I've tried swapping around and using the 21040, or a
different port on the other card, but it doesn't seem to change
anything.
