How do I debug a arm9 2.4.19 linux hang?

Question

Hi everyone,

I'm trying to debug this arm9 ... it's running some variation of Linux 2.4.19.

When I load a pci driver, the arm9 just hangs and reboots.

I've tried to enable to kernel hacking options in the menuconfig, but I don't see any error messages at all. Just a hang, and a reboot. That's all.

What else could I try? I've never done this type of debugging before..

There are some interesting tips here and here.

I would also recommend taking a look at this presentation on kernel oopsing.
