[1] [...] geode_aes is a PCI driver and should be automatically loaded if the PCI device it handles is present. However, since it also declares the alias "aes", when the crypto system attempts to load the "aes" module it may load this module and then wait for up to a minute for it to initialise and register the "aes" algorithm. geode_aes will never do this, since if there was a suitable device present it would already have been loaded. (The padlock modules don't seem to have the same problem because their module initialisation functions immediately return failure if the CPU doesn't support.) I believe geode_aes can be fixed by either (1) removing the MODULE_ALIAS declaration or (2) making the module initialisation function fail if the device is not present. The latter behaviour is generally wrong for PCI drivers, but this device presumably cannot be hotplugged. Ben. -- Ben Hutchings Logic doesn't apply to the real world. - Marvin Minsky
