    Well after looking at the syslog with full debugging turned on, it's clear
    that hotplugging is the culprit.

    So I disable the four USB 1.1 ports from the motherboard BIOS, and now I get
    a 4 minute boot, down from 9 minutes.

    So the I disable USB hotplugging with SuSE configuration to avoid my USB 2.0
    ports, and now I get a 1 minute boot.

    I review the HOTPLUG docs in SuSE 9.0 - practically zilch.

    I go to hotplugging at sourceforge,
    http://sourceforge.net/projects/linux-hotplug/
    and about the time the SuSE scripts were written signed off, there are
    threads about all kinds of problems with USB and delays - some from SuSE.
    There is a bug reported 25 July 2004 about this same issue. (997624)

    This explains the NOHOTPLUG and NOCOLDPLUG options in SuSE 9.1.

    So I say that SuSE sold a distribution with a buggy boot scheme, didn't
    provide a workable alternative, that they were aware of it, and are
    unwilling to acknowledge it. I would love to be wrong about this.

    Apparently (unverified) the use of multiple & mixed versions of USB hubs
    triggers the problem - standard features of my Gigabyte GA-7VRXP Rev 2.0
    motherboard.

    There are some indications that the problem also exists in SuSE 9.1 as well
    as other distributions that use hotplugging.

    I have spent quite a bit of time discovering this unpleasant fact, and I am
    very unhappy about it.

    Pressure from users (as well as the Linux community) has moved MS to improve
    their products and practices, perhaps it could work for SuSE/Novell too.
