[...] Thanks for narrowing it down to wait_for_completion() call, it was an useful hint. From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Subject: [PATCH] ide: fix hwif->gendev refcounting class->dev_release is called by device_release() iff dev->release is not present so ide_port_class_release() is never called and the last hwif->gendev reference is not dropped. Fix it by removing ide_port_class_release() and get_device() call from ide_register_port() (device_create_drvdata() takes a hwif->gendev reference anyway). This patch fixes hang on wait_for_completion(&hwif->gendev_rel_comp) in ide_unregister() reported by Pavel Machek. Cc: Pavel Machek <pavel@suse.cz> Cc: "Rafael J.
