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
