After lilo the boot hangs like this:

disabling CPUID Serial number....General protection fault:0000

[some cpu registry numbers]

kernel panic: attempted to kill the idle task! in swapper task not syncing.

My Cpu is a k7 900 slot A and my release is Redhat 6.2
with 2.2.14 kernel

Please, Help Me

Does this happen on the initial installation or once the install is finished and its starting up for the first time?

It take it that this happens everytime?

It souns to me like the installer is using a different kernel to the one that getting installed, and the one that is installed doesn't like something about your CPU.

Does the redhat install give you any options about what kernel to install? Sorry to ask you questions when I'm supposed to be helping out - I use Slackware and havn't installed RH since 5.2 was out! If there are any options try a different Kernel. Hopefully someone else in the forum will be able to tell you a nice way to do this, rather than going through the whole install.

HTH

Well Redhat doesn't give you any options for a particular kernel install, but you can try to see if you can boot into single user mode to check any other log files.
At lilo, type Linux 1 to boot into single user mode to find out if you can boot at all past the intial bootup.
