Kernel Oops and crashes

[Sasidhar Mukkmalla]

Hi,
We have many servers running with Intel 2.4GHz processor on ATX MBD 845E
chipset. These machines have 512MB ram and two hard drives of 200GB. All are
raided at level 1.

Our systems crash often and these are the messages I got from logs from two
different instances of crashes. Both these logs are from the same machine.
Any help to fix these problems would be greatly appreciated. Thank you
