This is more likely to be a udev-triggered kernel issue. If you try passing 'udevdebug' to the kernel command line, do you get more inforimation?

Comment 3 Andrew Jones 2010-05-18 14:48:10 UTC
Opening grub.conf to add the parameter I saw the problem isn't udev either. The problem is simply that the kernel's rpm script didn't grab the console params from the other kernels (console=tty0 console=hvc0).  So the boot didn't hang, it just stopped outputting. I just 'rpm -e'-ed the kernel and redid the rpm -ivh with the same rpm, and now the console params are there. I don't know what happened, but anyway, long story short, closing as NOTABUG.
