Posted this on amigans and hyperion forum without much response, so I guess I will try here also...

I am trying to fix the network driver for Napalm. Problem is, that it locks up randomly sometimes, but always on the call to OpenDevice.

I have described the issue here:

Strange thing is, that it does not happen, when I run that exact same code in a small example app. Also of course there is no way to tell, it this is a 68k vs ppc issue or what.
