This link: https://www.computerhope.com/issues/ch000474.htm suggests the problem is lower level than I thought (BIOS rather than OS, which may negate what I've written below). You could take a look and see if their suggestions help. Doesn't look like a fun problem to tackle, sorry. As they suggest, start reseating or better, disconnecting internal components one at a time in the hope the problem goes away on one of them. I use Knoppix ( http://www.knopper.net/knoppix-mirrors/index-en.html ) almost exclusively for rescue - I would give it a try. I'm inclined to suspect a hardware problem, and if you get the same error after burning Knoppix to a USB stick and booting, that would be ... well, a partial confirmation. Only partial because Knoppix is still, at its core (I think ...), Debian. If it does boot, you have a much friendlier and better equipped interface for system exploration and recovery than the pure Debian rescue package. -- Giles https://www.gilesorr.com/ [email protected]
