F7 crash investigation

[korgull]

Hi,

I installed yet another box with F7 but this new box has got a major issue, F7 
keeps crashing on it while windows works well on it.

Crashes occur about every 10-20 minutes and need a hard reset. They seem to 
occur at random, sometimes while booting sometimes just by looking at the 
screen...

I have slowed down memory and cpu freqs (was not overclocked) to see if that 
changes things, but it didn't.

Where do I start investigating this issue ?

regards,
Marcel

Look in /var/log/messages for kernel panics and other warning messages.

If there is a hang, it may be a kernel panic and it may be dropping 
debugging information into the system log.

I would start by running memtest86 on it and see what happens.

Please do not use the generic term "box". Be more specific; i.e.
laptop, desktop, server, make/model, etc.

Doesn't prove a lot I'm afraid - Windows and Linux load different bits
of the system memory with critical stuff

memtest86 for a day, official diagnostics, temperature readouts.

OK, I'll get busy with that.

Not many details that allows anyone to really help.

What video driver are you using?

Does it crash if you don't use compiz?

Have you tried to ssh into the "box" from another machine?

I ask these as I have the same issues but I can ssh into the machine and 
kill Xorg which will allow the machine to start working again.

I couldn't get much details because most of the time before I even could start 
working it crashed.

nvidia, I tried both the nv and nvidia driver with no difference.

I have used both KDE and GNOME, also no difference. I'm not sure if compiz was 
used though. I will check.

I tried but it wasn't responding.

I also ram memtest86 which completed without errors.

Yesterday I changed the network interface (it has two) and since than haven't 
seen any crashes. It may be coincidence though. 
The reason for me to change the network interface is that I noticed a crash 
occur at the moment I tried using the network. 
Anyway, since I switched the network interface it seems stable  (it's running 
for a couple of hours now).
