It indeed is! However, I'm doing some more testing before I say that disabling IDE Prefetch along with using Soren's 686B patch is the ultimate solution. Whatever the low-level technical reason for the problem is, it is highly strange. It's not really random, but it either *doesn't happen, or it will happen at a *definite*, predictable point. I could verify this both for the NFS crash you were looking at as well as with today's crash. As I have said on multiple purposes, I guess my mainboard's BIOS is a little more messed up than what is supposed to be standard ;-) This can also be seen by the fact that I need to put some light load on my hard disk in order to get an acceptably smoothly-moving picture from my TV capture card (though Soren's fix has acceptably fixed this problem by now, which I really appreciate!)
