I have a custom-built PC on which I've been running CentOS 4.x (kept up to the latest x) for a few years without any problems ... until this week.
Last week I was out of town on an extended trip, so I shut the machine down and powered off my UPS, etc. When I returned on Saturday, I turned everything back on, and the machine seemed to be booting normally ... and then it just very abruptly turned itself off, and refused to power back on. A short while later I was able to restart it, but again it shut down during boot. I *think* all that matters is that I've waited "long enough," but I was also moving the case around to open it so there's a slight possibility that something is loose and being jostled back into connecting (but I really don't think so).
After watching the boot messages carefully and comparing to rc.sysinit on a different CentOS 4 box, I've concluded that it's shutting down during loading of the "other" modules (after storage, network, and audio) parsed from the output of kmodule. Unfortunately rc.sysinit doesn't echo anything about what these modules might be.
The only thing that's changed is that I swapped in a new USB mouse because the buttons on the old one were getting glitchy, but I tried leaving that unplugged and the boot still stops at the same place with the same symptoms.
Does this sound familiar to anyone? Suggestions on what to do to either get past this or diagnose it further?

<snip> Does it croak before or after it hits the interactive option? If after, hit that I, and step through.

On the other hand, the symptom of refusing to power back on seems to indicate a hardware problem. I had a similar issue that turned out to be a bad power supply.

Try plugging the power in directly to the outlet, bypassing the UPS, in case the UPS itself has gone bad. (Bad UPS, Bad I say, BAD!!! :)

Thanks everyone, this doesn't appear to be a CentOS issue.
I went into the BIOS setup screen and watched the built-in hardware monitor for a while (hadn't previously realized it had this). It showed normal temps and PS voltages but reported that the PS fan is running slightly slow (1600RPM, though I'm not sure what it *should* be) ... and then after three minutes, it shut down. Voltages and temps never wavered so I'm not sure why the slow fan would result in a shutdown, but it clearly doesn't have anything to do with kernel modules.
