The machine is an AsusTP4N/P100/64Mb, Adaptec 2940, DE435 Ethernet, 2x 8 port
cyclades,
it acts as a dialin-server / router at our small ISP.
We have CONFIG_IP_ROUTER=y in our .config.
At the moment the machine is still running after this oops, without rebooting,
which confuses me, cause it normally crashes without something written to the
syslog.
We use gcc-2.7.2, libc-5.2.18. The machine does ppp and [c]slip.
Email me if you need additional details.

regards,

-Michael
