I was too lazy to bisect for bad commit;) Reading the code I found problematic kthread_should_stop call from netlink connector which causes the oops. After applying a patch, I've been testing owfs+w1 setup for nearly two days and it seems to work very reliable (no hangs, no memleaks etc). More detailed description and possible fix is given below: Function w1_search can be called from either kthread or netlink callback. While the former works fine, the latter causes oops due to kthread_should_stop invocation. This patch adds a check if w1_search is serving netlink command, skipping kthread_should_stop invocation if so.

Pull ARM SoC i.MX DT changes from Olof Johansson: "This branch contains of devicetree changes for the Freescale i.MX platform. The base patch of the branch changes the format of the dts files to a slightly different format that makes it easier to do derivative board definitions, but it also introduces a lot of churn in the process since every line of the file is touched. On top of that are a handful of the regular changes; enabling more boards as DT-based instead of legacy board files (mx25pdk), enabling another driver for devicetree and thus adding bindings (onewire), etc. I'm not happy about the churn, and will likely not take it for other platforms in the future." * tag 'late-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: dts: add dtsi for imx6q and imx6dl ARM: dts: rename imx6q.dtsi to imx6qdl.dtsi ARM: dts: i.MX6: Add regulator delay support ARM: dts: Add device tree entry for onewire master on i.MX53 ARM: i.MX53: Add clocks for i.mx53 onewire master.

2013-01-15drivers/w1/masters/mxc_w1.c: use devm_ functionsJulia Lawall
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. At the same time, this fixes two faults. First, mdev, the result of kzalloc, was never freed. Second, on failure of ioremap, 0 was returned. This has been replaced by -EBUSY, which was the failure value for the call to request_mem_region, with which the call to ioremap has been combined. The warning message on failure of ioremap is dropped, because devm_request_and_ioremap already gives such messages on failure. Finally, the initial call to platform_get_resource is moved closer to the call to devm_request_and_ioremap, which takes care of checking whether its result is NULL, implying that a test on the result of this call to platform_get_resource is not needed.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core changes from Greg Kroah-Hartman: "Here's the big driver core pull request for 3.6-rc1. Unlike 3.5, this kernel should be a lot tamer, with the printk changes now settled down.
