Hi,
git bisect proved that the patch
commit 40f122f343797d02390c5a157372cac0c5b50bb7
Author: Alan Stern <[EMAIL PROTECTED]>

USB: Add autosuspend support to the hub driver
This patch (as742b) adds autosuspend/autoresume support to the USB hub
driver. The largest aspect of the change is that we no longer need a
special flag for root hubs that want to be resumed. Now every hub is
autoresumed whenever khubd needs to access it.
is the cause for IRQ #10 being disabled on my notebook:
