Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

OK, I'm new to all of this myself, so don't take my word as gospel.
Have you checked that you only have the sound cards/services you need in /etc/modules.conf? Commenting out those you don't might be an idea.
I don't know why this could cause a system crash, but then, there's a lot I don't know...
If you do a google for "Can't locate module sound-slot-1" there is some info on that. I don't know if that is causing the problem. If you know someone that has a nvidia driver you might see if they are getting similar messages in the relevant nvidia lines above. I don't have your driver but don't have any messages like that. Seems to be an error code while loading nvidia.
Thanks for the insight. How do I handle submitting a bug report?
I haven't made any hardware changes since I installed Fedora back in Feb. Strangely, I also haven't had this problme re-occur since the 25th (it;'s now the 28th).
I had tried moving around some configuration files from my home directory (in respose to another thread I had posted) and things seem back to normal. I never really ended up changing anything, so I don't know what the heck "fixed" the problem I was having....Man I hate when that happens...
Anyways, thanks for replying. Pleasae advise on how to submit the bug report, and whatever else you think I ought do here.
First off I do not think this is a software problem. I deal a lot with hardware and I would take a guess that you may have a problem with your power supply. Most modern processors have very high demand on the 5V line and this is especially so during the boot phase. A modern processor can demand very high currents at 100% load and if there is a problem on the 5V line then it leads to computational errors. Under normal circumstances you would not have any problems because the processor never approaches a 100% usage. What I find is that PSU's can degrade over about a year and then funny things start happening that cannot really be explained. It happened in my own system recently. Ideally you need to monitor your system with an app like gkrellm under full load with an app like cpuburn. If your 5V line starts to fall below 4.85V then more than likely you have a problem. If you don't have gkrellm then go into your bios and have a look at the health status. If you are getting idle readings around 4.9-4.95 I would be very suspicious. You can also run checks on your memory with memtest86.
Wow, that's the kind of in depth analysis I like to see!
I'm an electronic tech, so here's a question for you...
Any adverse effects that you can imagine from sticking my DMM (digital multi-meter) on the 5v line and monitoring that way? It's a bit more real-time and I'd trust it more than the interpretation of a program.
GREAT reply, and makes a tremendous amount of sense to me. Good to see somebody thinking outside the usual...
Got my DMM sitting on there now. Currently, just after a reboot, it's at 5.06V. The problem is, in the early stages of the boot process (from POST to new hardware check), it was ramping up and down from ~7.5 all the way to ~13V!! Any ideas as to what could be causing this? Are there some bi-direct level-shifters on the Mboard that are getting set in the wrong direction? Any other thoughts?
It has yet to dip below 5, so I'm ruling out supply droop. This line being pumped up by something has me concerned though. Having never dealt with this much, I don't know whether my concerns are warranted or not. I know that the line will obviously have a good amount of ESD protection, so I'm not really worried about it damaging anything, but I'm worried that it is a symptom of something else.
I'd really appreciate anybody/everybody's experience here. Let me know what ya'll think.
If you don't have monitoring software around then using a MM you can get readings off the mosfets. The mosfets are the black things with 3 legs on them and they are in pairs around the area of the processor. This is NOT A RECOMMENDED THING TO DO - IF YOU CAUSE A SHORT CIRCUIT YOU COULD DAMAGE M/BOARD & PROCESSOR. Apply one probe to right leg and the other to the centre leg (facing the legs). If the reading is negative switch the probes around. The mosfets stabilise the current to the processor.
If you are getting massive swings in the 12V line this can also be a major problem because that feeds your hard drives and can cause corruptions.
hmmm, my 12v line is at a constant 12.46V. A bit high, obviously, but a problem?
BTW, I'm just probing on the extra power connector (like that which goes onto a CD Rom drive) to get the voltages. I assume these are all more or less in parrellel with everything on the board, so is this a sufficient spot to probe?
As long as the voltages are within 10% of spec then its not a problem. If you were getting readings of 7.5 - 13V on the 5V line then there is something seriously wrong. There is nothing that would feed back on the line. The PSU is designed to stabilise the supply within limits. I have done a lot of overclocking and this is the one area that is critical to getting max performance out of a processor. Have even played with 2 PSU's feeding a m/board one for the hard drives and the other just for the cpu. One of the biggest failures of commercial manufacturers is decent PSU's. If you are running an Athlon or PIV the PSU should have a minimum of 200W on the 3.3&5V line.
