: The values in the RA & PC are probably accurate & they could indicate : that something followed a null function pointer. I would assume it's a kernel function. I naively assume a long jump to a null pointer in user space would result in the crash of the user program (cp in this instance) but not a kernel panic. : Maybe you could provide more details? Like kldstat output & perhaps Sure! I can even provide you with a login to that box if you so desire. I'll disable the mount of swap and you can get crash dumps too. : module? Are you certain your modules match your kernel? If they or : anything else is loaded as a module, can you try compiling everything : (but osf/1) into your kernel statically? Everything is static. I was agressive with the removal of things from my kernel config, but I don't think I nuked anything something else was depending on. Removing things like FFS_ROOT may have very creepy side effects. It has been running fine up to this point.
