It turns out that I might have over-reacted to a faulty CPU temperature sensor before. I verified today (while working at the console) that Ghostrider itself wasn’t crashing; the UPS it was connected to was. I’d just put batteries in it about a year ago and now this? It’s now connected to house current and should be more stable. It’s CPU temp was showing in the high 90’s (°C) but now it’s showing in the high 40’s.

Not that it wasn’t a good thing to get in there and clean and put some thermal paste in…
