| From: Neil Bird <neil@xxxxxxxxxx> | Ordinarily, I'd say that this sort of thing is hardware related, and | although I will be trying memtest for a while over the weekend, I'm suspicious | that this has only started happening immediately after I upgraded from Fedora | 8 to Fedora 10. Memtest seems like a good idea. | I'm running 'nuvexport', which is a script that pulls in MythV recordings | and spits out normalised video files; in this case, an XVID AVI using (I | think) ffmpeg. Several minutes into the run, the PC just ups and reboots. | This has now happened twice, and has never before. Could still be hardware: that might be a heavy CPU load compared to what you normally do and that might tickle thermal problems. | I will also be trying the run from init level 1 just to make sure nothing | else running might be affecting it. 1? 3 seems less drastic. Or even just ctrl-alt-f2. | But the question is: if there *is* a bug (kernel?) that's letting a | user-mode process reboot the machine, how to track it? If it is a panic, and you are using console mode, you ought to be able to see what happened. Alternatively, the traditional technique is to use a serial console. This has the kernel use the serial port as a console. For that to work, you need to have a serial port built into the motherboard (USB serial port won't do) and you need a "terminal" to attach to the serial port (these days the terminal is generally just another computer). Failing that, you can try kexec/kdump/crash. In theory this is a great solution that should work with any machine. In my experience, hardly anyone uses this mechanism so it didn't work out of the box in Fedora 7. Here are a couple of old bugzilla entries I made: https://bugzilla.redhat.com/show_bug.cgi?id=244464 https://bugzilla.redhat.com/show_bug.cgi?id=244524 See http://fedoraproject.org/wiki/FC6KdumpKexecHowTo I don't know if things are better now.
