Hi parisc-linux,

I tried to upgrade my C240 (from old 2.4.19-pa2) to linux-2.4.20-pa10 and
linux-2.4.20-pa13 (compiled with gcc-3.2.2-pre). Both new kernels boot
up fine, all daemons/programms seem to work, even network is up, but the
C240 (beast) instantly hangs after I try to ssh into the beast from my
Intel laptop (bucephalas).
Both systems (PA-RISC and Intel) are debian/sid, apt-get upgraded on Dec 8.
I tried the following on the laptop:

==
bucephalas:/home/xam/parisc# ssh xam@beast
xam@beast's password:
Warning: No xauth data; using fake authentication data for X11 forwarding.
==

The ssh authenification is obviously successful, but I won't get a shell prompt
since the C240 crashes immediately after the login.

It works when booting the old linux-2.4.19-pa2, so there must be a bug
introduced between 2.4.19-pa2 and 2.4.20-pa10.

Attached are the kernel stack/register dump and parts of the System.map
when running linux-2.4.20-pa13.
I didn't include the kernel config since it is quite large, but the only
thing that has changed is that I use SYM2 instead of SYM1 on 2.4.20-pa13.
The config of 2.4.20-pa10 (not working) and 2.4.19-pa7 (working) is the
same, and it hasn't changed for quite a while since before that and always
worked.

greetings max
