Remembering tales from long ago - how updating an OS often seemed to induce faults in hardware that was apparently working fine before. There's many reasons why this may be the case. The newer code is poking different areas of memory than before. Previously a memory fault existed, but not in an area that you noticed (maybe one pixel in the display never worked) and the system didn't throw a tantrum about, but now that bit of RAM is being used by some important operating system process. I've experienced this kind of thing (one install worked fine, apparently, even with RAM that tested as faulty, the next install did not). And, of course, there's things like manufacturers releasing faulty hardware that fails on a newer driver thanks to happenstance that the prior driver didn't provoke. The install process was CPU intensive for a prolonged time and stressed something on a system that has spent most of its time the last few years just idling only. A heatsink wasn't good enough, or clogged up with fluff, or not fastened properly, or the thermal paste dried out or wasn't applied well in the first place, or the cooling fan was failing, and the CPU overheated. Some power filtering component on the edge of dying, did. A vibrating DVD drive finally weakened some bad soldering joint... And another one I've experienced: Prior to an upgrade, you've picked up the box and cleaned it, or just moved it. The box isn't rigid, it twists a bit, and some of the daughter boards aren't properly seated to the motherboard any more (video cards, memory cards, etc). This also happens when the ambient temperature changes a lot - things creep out. Even a CPU socket can go bad, and I'm surprised this doesn't happen more often, considering the huge cooling devices that are crushed onto them, these days. As far back as the old Apple ][ it was a common debugging procedure to re-seat all the cards and socketed chips, to fix odd failures. Also, some cards didn't have very good edge connectors, cleaning them often made things better. I remember a range of Macs had problems (as they aged) with the factory soldering not being up to par. People would remove all the plastic parts and back the motherboard in an effort to re-flow the solder. I was given one in that condition, but decided it wasn't worth the pain to try and fix. Solder faults on complex machine boards tend to be everywhere, not just one spot. Often caused by the solder being too contaminated on the build day, or wrong temperature, or the boards being contaminated. Things sometimes just age and fail from cumulative decay. So, come OS install and update times, I tend to open a box, inspect heatsinks, clean it, and reseat all the connections. Having a spare power supply to swap over is handy, too. They don't always age well, especially the bargain basement types. -- uname -rsvp Linux 3.10.0-1160.102.1.el7.x86_64 #1 SMP Tue Oct 17 15:42:21 UTC 2023 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
