FC6 freezing at bootup (sometimes)

[Ryan Li]

I'm running FC6 on my iMac and have rEFIt installed.
I can choose Mac OS X or FC6 from the rEFIt boot menu.
If I choose to boot into FC6 it often freezes at 'Red Hat nash version 
5.1.19 starting'
But if I boot into Mac OS X and do a restart and then choose FC6, there's no 
problem.
Is there a simple fix to make it to where I won't have to first boot into OS 
X?

Thanks_
Ryan


P.S. It also says this right before it freezes:
