In recent kernels the 1-wire kernel modules do not work any more. The module wire got broken in 3.11-rc1 and 3.12-rc1 introduced a further problem:
1: 3.11-rc1 introduced the automatic loading of slave modules. This blocks modprobe, because request_module is called with a locked mutex of the w1 master. Loading of the slave module calls w1_register_family, which calls in turn w1_reconnect_slaves and there mutex_lock(&dev->mutex) will wait forever.... 2: 3.12-rc1 introduced w1_bus_notify which assumes that all slaves have fops defined. This is not the case for e.g. w1_smem and maybe also breaks custom written modules. This very small patch set is split in 2 parts: PATCH 1/2: w1 - fix fops in w1_bus_notify fixes problem 2 above PATCH 2/2: w1 - call request_module with w1 master mutex unlocked fixes problem 1 above Please include these patches in 3.12-rc4 and in 3.11 stable.
