I installed fedora12 on a XEON server with raid10 (i'm not sure).
Then everything works fine until a kernel panic is shown on my keyboard.
The server is still working, outputting on my monitor, and everything else is working fine, except that i cannot use my keyboard so i cannot configure the server.
i have no mouse nor shell daemon supporting the mouse and i cannot say if the mouse is working. i changed the keyboard with new but again all three leds (scroll lock, caps lock and num lock) are blinking.
this kernel panic happens on different stages. sometimes when i load operating system a kernel panic occurs so i cannot log in through tty.
sometimes i have enough time to start ssh server or to chkconfig it so when kernel panic occurs i'll be able to connect remotely.
If i start the server and load operating system (by grub) then start ssh i can log in remotely while the kernel panic is on and can use the server totally.
i have installed the newest kernel 220.127.116.11 by compiling it. the same thing happens again.
such kernel panic may occur 2 minutes after the os is loaded or hour and a half after that. its on random basis.
as i know there are 2 (maybe more) types of kernel panics: soft and hard.
i suppose this is a soft kernel panic because everything works when it occurs. the interesting is that when this kernel panic occur there are no new messages on my monitor about the kernel panic but other messages from the ordinary programs started.
for example i compiled my new kernel in a few stages:
i logged in and configured the kernel (menuconfig) and then ran make.
while the make was active a kernel panic occured but new messages about the compiling process were blinking on my monitor so the compilication process was running anyway. and so with few restarts on every step of compilation (make menuconfig, make, make modules...) a kernel panic occured.
I'm stuck now.Does someone of you have something on mind about this problem ?
have a nice day.
