Best we can do is cc various USB people then wait. Things are slow at
present due to summer migratory activity towards Ottawa.
But when the flock returns, hopefully they will remember that we have a
straightforward box-killing regression in the 2.6.17 OHCI controller quirk
handling.

It's hard to come up with a fix without knowing what's wrong. The current
development version of that subroutine is essentially the same as the
version in 2.6.17.
If you want to pin down the problem more precisely, try adding a whole
bunch of printk() statements to the quirk_usb_handoff_ohci() function in
drivers/usb/host/pci-quirks.c.

Andy, please add the below, work out what line it gets stuck at and then
let us know? Thanks.
(bear in mind that our line numbers will usually be different from yours,

More likely in some other code, since that "quirk" handling code hasn't
changed in forever. Sometimes BIOS changes hurt (including setup/config),
sometimes pci/acpi init is a factor.

Well I did that and the kernel got a lot further! It ran through the
pci_init stuff without a hitch and then hung just after this line was
output:
ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver
(PCI)
So I littered drivers/usb/host/ohci-pci.c with similar debugging and the
last line it printed was from (marked with --->):
static int __init ohci_hcd_pci_init (void)
{
int ret;
printk (KERN_DEBUG "%s: " DRIVER_INFO " (PCI)\n", hcd_name);
if (usb_disabled())
return -ENODEV;
D();
pr_debug ("%s: block sizes: ed %Zd td %Zd\n", hcd_name,
sizeof (struct ed), sizeof (struct td));
---> D();
ret = pci_register_driver (&ohci_pci_driver);
D();
return ret;
}
IE it never returned from pci_register_driver.
A bit more sprinkling of debugging showed it got to drivers/base/bus.c
(bus_add_driver()):
D();
driver_attach(drv);
D();
It never returned from driver_attach().
More debugging in drivers/base/dd.c showed the last output to be (marked
with --->):
static int __driver_attach(struct device * dev, void * data)
{
struct device_driver * drv = data;
/*
* Lock device and try to bind to it. We drop the error
* here and always return 0, because we need to keep trying
* to bind to devices and some drivers will return an error
* simply if it didn't support the device.
*
* driver_probe_device() will spit a warning if there
* is an error.
*/
---> D();
if (dev->parent) /* Needed for USB */
down(&dev->parent->sem);
D();
IE it never returned from down.
So why did putting in the initial lot of debug alter where the kernel
hung? And what's next?
NB a reminder: 2.6.16 boots up fine on this machine.

Any progress? FWIW I did notice a pause at:
Booting processor 1/2 APIC 0x1
on 2.6.17 - the pause isn't present on 2.6.16.

I don't know why the location of the hang changed. It suggests you're up
against some kind of race against the hardware.
The new location you found is in the driver core, and a bug was fixed in
that region just about at the same time as you ran your test. You might
try redoing everything with the current -mm tree plus hotfixes.
And try running each test a few times. If there is a race, you could get
different results each time.
