ipwireless_network_create() is never called in atomic context. The call chain ending up at ipwireless_network_create() is: [1] ipwireless_network_create() <- config_ipwireless() <- ipwireless_attach() ipwireless_attach() is only set as ".probe" in struct pcmcia_driver. Despite never getting called from atomic context, ipwireless_network_create() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
