Haven't had the time to investigate further yet, sorry.

Here's the result of git bisect:

[PATCH] USB: allow usb drivers to disable dynamic ids

This lets drivers, like the usb-serial ones, disable the ability to add
ids from sysfs.

The usb-serial drivers are "odd" in that they are really usb-serial bus
drivers, not usb bus drivers, so the dynamic id logic will have to go
into the usb-serial bus core for those drivers to get that ability.

Please note that with the above changeset, hal and udev daemons refuse
to start up during boot so I don't even have /dev/sda2 when plugging in
ipod.

That's _really_ odd, as hal, udev and dbus all work just fine on my
machines with the above changeset (actually with 2.6.16-rc4). And that
changeset should not have caused anything to change with regards to the
core uevent code, as it's a usb-serial change only.

And you don't even have CONFIG_USB_SERIAL enabled... Very odd.

If you revert this one patch, on top of a clean 2.6.16-rc4, do things
start working for you again?

thanks,
