Close to identical. If FreeBSD 1.0.2 suffers from what look like VM problems on one machine (actually two, if you count disk controller/motherboard swaps) would there be any hope that NetBSD might work better? At this point I'd even settle for different 8-) It's always worth a try, I suppose, but I rather doubt that what little VM differences there are between the two would solve your problems. I'm referring to the problem of GCC getting segmentation violations while running make world. I've swapped out the disk controller, motherboard and memory, and so far only succeeded in making the problem worse 8-\ Admittedly, the memory swap took the system from 16M to 4M bytes, but it seems that if faulty memory were the I think the 4MB decrease is your problem - it's a known thing that gcc2 doesn't live well with 4MB systems in FreeBSD 1.02 (this has undergone significant work in the upcoming FreeBSD 1.1) - you can either repopulate your machine with 16MB and see if the problems persist, or go to gcc1 (available as a package on freebsd.cdrom.com) and see if its decreased memory needs sort you out - I've heard of some folks getting good results with that..
