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.

| | | | | | | | | | | | | | | | | | Commit 8a1861d997 ("w1-gpio: Simplify & get rid of defines") removed the compile guards from the device-tree id table, thereby generating a warning when building without device-tree support.

| | | | | | | | | | | | | | | | | | | | | | | | Commit 8a1861d997 ("w1-gpio: Simplify & get rid of defines") changed (apparently unknowingly) the driver to a hotpluggable platform-device driver but did not not update the section markers for probe and remove (to __devinit/exit, which have since been removed). A later commit fixed the section mismatch for probe, but left remove marked with __exit.

As a result, if you boot with USB cable on and load g_ether, the connection does not work as the code thinks the cable is off and the phy gets powered down immediately. This is a major regression in 3.9-rc1. So the proper check should be: exit if _glue is NULL, but if it's initialized we memorize the status, and then check if the musb core is ready.

The commit effectively added a large number of Huawei devices to the deprecated usb-storage mode switching logic. Many of these devices have been in use and supported by the userspace usb_modeswitch utility for years. Forcing the switching inside the kernel causes a number of regressions as a result of ignoring existing onfigurations, and also completely takes away the ability to configure mode switching per device/system/user. Known regressions caused by this: - Some of the devices support multiple modes, using different switching commands. There are existing configurations taking advantage of this. - There is a real use case for disabling mode switching and instead mounting the exposed storage device. This becomes impossible with switching logic inside the usb-storage driver. - At least on device fail as a result of the usb-storage switching command, becoming completely unswitchable. This is possibly a firmware bug, but still a regression because the device work as expected using usb_modeswitch defaults. In-kernel mode switching was deprecated years ago with the development of the more user friendly userspace alternatives. The existing list of devices in usb-storage was only kept to prevent breaking already working systems. The long term plan is to remove the list, not to add to it.

In a couple of places, the driver compares the DMA address stored in a QH's overlay region with the address of a particular qTD, in order to see whether that qTD is the one currently being processed by the hardware. (If it is then the status in the QH's overlay region is more up-to-date than the status in the qTD, and if it isn't then the overlay's value needs to be adjusted when the QH is added back to the active schedule.) However, DMA address in the overlay region isn't always valid. It sometimes will contain a stale value, which may happen by coincidence to be equal to a qTD's DMA address. Instead of checking the DMA address, we should check whether the overlay region is active and valid. The patch tests the ACTIVE bit in the overlay, and clears this bit when the overlay becomes invalid (which happens when the currently-executing URB is unlinked).

After a QH has been unlinked from the async schedule and the corresponding IAA interrupt has occurred, the controller is not supposed access the QH and its qTDs. There certainly shouldn't be any more DMA writes to those structures. Nevertheless, Intel's controllers have been observed to perform a final writeback to the QH's overlay region and to the most recent qTD. For more information and a test program to determine whether this problem is present in a particular controller, see http://marc.info/?l=linux-usb&m=135492071812265&w=2 http://marc.info/?l=linux-usb&m=136182570800963&w=2 This patch works around the problem by always waiting for two IAA cycles when unlinking an async QH. The extra IAA delay gives the controller time to perform its final writeback. Surprisingly enough, the effects of this silicon bug have gone undetected until quite recently. More through luck than anything else, it hasn't caused any apparent problems. However, it does interact badly with the path that follows this one, so it needs to be addressed.
