Kernel crashed, but no oops information!
I have tried for several days, and I have googled hard, but I can't find the results. So now let me describe my problem as follows:
I have installed an Ubuntu 9.10 on a VMWare machine (system A), and I have installed a Redhat 9 on a VMWare (system B, and yet I have installed an Ubuntu 9.10 on a physical machine (system C).
And I use painic(...) function and/or use die_nmi(...) function in a driver module or in the kernel, also I have tried using the command "cp /dev/zero /dev/mem".
In my testings, all my above methods can crash Linux kernel (keyboard and mouse are dead), but in all the cases, there is no oops information at all.
For system A and system B, the screen remains just as before crash, I mean, the screen is still the desktop and etc.
For system C, system reboots quickly.
So I am strange that how can I see oops information.
