If you've got a PCI ethernet board sitting around - I can personally vouch for 3com 3c905 based cards to work just fine, others used DEC 2114x clones.
I'm right now building a kernel on the O2 and installing some pre- fetched stuff from pkgsrc at the same time. It has been running for quite a while and no hangs so far, so you're probably right.
After that I'll try to do some heavy network IO.
In theory anything supported by NetBSD should work but since the O2 is a little more ticklish than - say, macppc and sparc - regarding DMA and cache synchronization ( macppc for instance is always DMA coherent ) I'd expect occasional trouble.Any change with the 2nd patch?Well, I wanted to keep that machine self-hosting and so far I've been unable to checkout the kernel sources :-)Eh, you won't be impressed by build times.
Indeed. My 68030@50 Amiga compiled faster (well, probably the reason is that gcc2 is much faster than gcc4)
