Subject2.0.0 OOPS - AX.25 related (I think)

My system is an AMD486DX/2-80 running Red Hat 3.0.3, upgraded to 2.0.0
kernel. I've had the ax.25 stuff up and running for 2 days now with
the ax.25-utils-2.0. Last night I left a popclient running on a poor
link. This morning I found this OOPS in my logs:

Unable to handle kernel NULL pointer dereference at virtual address c0000059

I'm guessing here that sl_header is refering to a SLIP header,
therefore I'm assuming this is an ax.25 problem.

Also, probably not related (slip is compiled in, not a module),
kerneld won't run anymore either:
