One of the machines I administer today paniced as described at
the end of this message. 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.
