Another > information I'd be happy to get :-) Kernels in general can know about ECC errors. Tru64 e.g. handles them. So the hardware is there. I once had dodgy memory in a AS2100A which FreeBSD crashed on. But Tru64 and VMS ran on the same hardware OK. This was a while ago, I'm not sure if there have been changes in this area.
