I have a 486DX4-100 machine running FreeBSD-2.1R. I experienced the same problems. I had to disable both the internal and external caches, of my machine. It then worked find. I have another 486DX2-66 older machine, that keeps getting those signals, even with both caches disabled. Can anybody tell me where is the list of machines that are currently running FreeBSD with no problems?
