Hi... What would it take to either create software for debugging hardware, and/or add appropriate debugging to the kernel that would improve debugging of hardware problems? Erk...as far as software is concerned, maybe something that you could run in single user mode that would completely thrash the RAM, doing read/writes to *all* the memory looking for any corruption? Or something else that could be turned on against /dev/rsd0b to totally thrash the swap space on a drive? As far as the kernel is concerned, I'm getting panics in VM and keep getting told its hardware problems...fine, but there *has* to be a better way of isolating the problem then replacing bits and pieces until the problem seems to go away. For instance, when I get a VM fault...what exactly *is* the problem? Is it a problem with the swap space (ie. hard drives) or RAM? My -stable machine is a 4 month old computer, and all the parts are new in her...last I've been asked is "when am I going to replace the machine"...replace it with what? its all new...if there was some way of narrowing down the offending parts and replacing those, that would be great...but just going out and buying a new machine is not the answer, cause the part that is wrong with *this* machine might exist in the next machine *shrug* Does this make any sense?
