TS7200 panic on 5.1.0

I just installed NetBSD 5.1 on a TS7200. I built the kernel with a trimmed down .../evbarm/conf/TS7200 kernel config (attached). Every so often on reboot, I get a fatal kernel error (see below). It also happened once while installing a package.

How can I start debugging this?

If possible, please point me to some resources to read up on to get me started with landing this in a debugger.

Thanks â Joel
