A dmesg follows that. I was not running a debugging kernel at that time, but I have compiled one and installed it. I cannot reboot the machine since it is a production box, but if the crash happens twice more I will have a debug kernel in place to analyze the problem. Does anyone have any ideas what the problem might be? Thanks in advance.
