No. This change made no improvement in the problem I am
encountering. I think Christoph Hellwig may be onto
something, though. He is exploring a Yenta/3c575 interaction.
The lockup only occurs when the 3c575 card in present in one
of the PCMCIA slots during boot.
Here's my /var/log/messages info from that hung boot cycle:
