2.6.18.1 linux hangs

[rheneus.paul at gmail.com]

In FC6, some times the linux hangs at bootup after the "Uncompressing  
linux ..." and before the "Red Hat nash version ..".

It's not happening always, I've enabled kernel debug and loglevel to print  
more detailed information. If it hangs again, I would attach the detailed  
log information.

Throw some light on what could be the issue, so that I can debug more on  
this.
