I've just booted with the irqpoll kernel option and again it hangs at the
"Preparing Restricted Drivers" step for about 10 minutes. Aside from that,
nothing appears any different from the output previously posted, except that
I don't receive any warnings about disabling irq 23. I would consider this
an acceptable workaround if it wasn't for the 10 minute boot-up time.
Here's the info I have one more time (this is while running with the irqpoll
kernel option):

I've also attached /var/log/messages in case it is helpful.
