All Machine crashed either due to hardware or software
problem. We can trace out the h/w failure as the BIOS or
kernel will report that a device had failed or is missing.
Knowing at which stage of the boot process a failure
occured is very important. If we get Kernel Panic Error it
means (a) an incorrect root argument to the kernel (b)
missing modules from the initial RAM DISK.If problem occurs
during file system mounting that means something wrong
happen during execution of /etc/rc.d/rc.sysinit(this script
does a lot) Once system services began to start the failure
is most likely in /etc/rc.d/rc.sysinit
Check the log files /var/log/message and dmesg bcoz
information gathering is very important to trace the bottle
neck of the issue.
