Thanks. This is a bug in iwlwifi. The problem is actually another case where my workqueue debugging with lockdep is triggering a warning :)) Here's the thing: iwl3945_cancel_deferred_work does cancel_delayed_work_sync(&priv->init_alive_start); (which is the "(&(&priv->init_alive_start)->work)" lock) but it is called from within a locked section of mutex_lock(&priv->mutex); (locked from iwl3945_pci_suspend) On the other hand, the task that runs from the init_alive_start workqueue is iwl3945_bg_init_alive_start() which will lock the same mutex. So the deadlock condition is that you can be in cancel_delayed_work_sync() above while the mutex is locked, and be waiting for iwl_3945_bg_init_alive_start() which tries to lock the mutex. johannes
