kernel process memory overrun debugging

[Yony Yossef]

Hi all,

I'm looking for methods to debug a kernel process memory overrun.
I'm working on an Ethernet driver for FreeBSD 7.0 and I'm facing a crash
after several (kldload + kldunload)s.
The exception is being thrown by the shell process after the last kldunload
successfully ends so I'm guessing it's a memory overrun.

Is there any tool/kernel option that helps?
Thanks,

Yony
