4 A couple of strange things
- I have found out that the default run level was set to 3. When, as a root I tried 'telinit 5', the machine responded with a blank screen. I had to reset.
Have you tried a <CTRL>-<ALT>-<F1> when this happens? Since desktop is being started on tty7, if it fails and seems blank, maybe switching to virtual console 1 will work, if the machine is still alive.
This symptom actually sounds exactly like what has been happening on my laptop when no networking is available at boot time. It could be unrelated to the panic problems.
- Rebooting the machine was accompanied with messages regarding ntp/clock skew. Later, I have found out that I have lost the network connection, probably while playing with the installation, so this probably explains the clock skew. Am not sure if this has any relevance.
It's probably not relevant to the panics but it could be producing other symptoms that are confusing the diagnosis. Try to get it fixed again if you can.
Bill's advice (e.g. about checking hardware connections) is good.
I am memtest'ing the machine again for the night. We'll check the connections first thing tomorrow. And will follow with an attempt to boot to centos 5 keeping close watch on the network.
