I have a vague feeling that this was fixed, perhaps in 2.6.24.x?

Obviously not in 2.6.24.1, and I thought that 2.6.24.2 just added the fix for the vmsplice
exploit. So unless 2.6.24.3 has been released...?

Never heard of this, what is the initialization script that causes this?
Also do you have the SYSFS_DEPRECATED option configured? that caused issues
with regular network drivers.

Yes, SYSFS_DEPRECATED is enabled. And the init scripts are from Fedora 8.

There was a bug (fixed in 2.6.24) that had to do with sysfs_create_link
and SYSFS_DEPRECATED probably there is a similar problem with directories.

Chris, could you enable CONFIG_DEBUG_KOBJECT=y, it might show what
objects try to claim the same name.

Greg,
it seems that:
arch/x86/pci/legacy.c :: pci_legacy_init()
tries to create already created "bridge" symlinks in 2.6.24. So we
discover the same devices twice? Can this be a reason for the hang?
I guess in 2.6.25, the warning is gone with:
commit fd7d1ced29e5beb88c9068801da7a362606d8273
Author: Greg Kroah-Hartman <gregkh@suse.de>
Date: Tue May 22 22:47:54 2007 -0400
PCI: make pci_bus a struct device
This moves the pci_bus class device to be a real struct device and at
the same time, place it in the device tree in the correct location.
Note, the old "bridge" symlink is now gone.
Thanks,
Kay

No, it can't be because it's *not* hanging in this configuration :-). It hangs when I *don't* add
the acpi=noirq option, whereas here it's just adding noise to the dmesg log. (I'm guessing Linux
doesn't call pci_legacy_init() when ACPI takes charge of the IRQs.)
Cheers,
Chris
