Long Pause at Boot

[Khoa Ton]

Hi all,

I'm noticing a long pause, about 20 seconds, on boot up right
after the line:
	"Uncompressing Linux, Ok booting kernel"

This is happening with my current kernel 2.6.17-1.2145_FC5,
but NOT on the previous kernel 2.6.17-1.2139_FC5, and
WAS pausing on the kernel before that, 2.6.17-1.2133_FC5.

I've tried dmesg to see if I can pin point the pause,
but that was not help.

Can anyone point me to debugging this annoying, but
harmless, pause?

Thanks,
Khoa Ton
