The Linaro Kernel Working Group (KWG) is excited to announce the availability our October 2011 development snapshot:
linux-linaro-3.1-2011.10-1
As the word "snapshot" implies, these are meant as development kernels and have not been fully validated. You should expect issues and to help us deliver a better kernel in the future, please file bugs in Launchpad at https://bugs.launchpad.net/linux-linaro.
The source tarball is available at: http://launchpad.net/linux-linaro/3.1/3.1-2011.10/+download/linux-linaro-3.1...
The kernel sources can also be accessed using git at: git://git.linaro.org/kernel/linux-linaro-3.1.git tag: linux-linaro-3.1-2011.10-1
In addition to an update to the 3.1 (-rc10) kernel, this kernel includes the following changes that are queued up for 3.2:
- An EHCI slowdown workaround from Ming Lei
- Thumb-2 undef handling fix for multi-CPU kernels from Dave Martin
- ARM cpu topology definition from Vincent Guittot
- RMK's devel-stable branch from last week that contains (among others):
- Runtime consistent dma size init from Tixy
- boot_params to atag_offset transition froma Nicolas Pitre
- ARM pmu/perf updates from Will Deacon
- The ability to append a DT to zImage from Nicolas Pitre
- The ARM kprobes test infrastructure from Tixy
- Suspend/resume consolidation and cleanups from RMK
- cpu pm notifiers on ARM from Colin Cross
A full change log against the 2011.09 release is available at: http://launchpad.net/linux-linaro/3.1/3.1-2011.10/+download/CHANGELOG-linux-...
High Priority Known Issues:
- We have seen issues with boards not rebooting in our CI lab but so far Nicolas has been unable to reproduce it on his systems and we've not seen any reports of this on upstream 3.1-rc trees. Please download and test the kernel on your platforms and add notes to the following LP bug if you are able to reproduce this:

Questions? https://ask.linaro.org/
This tree seems to be missing per board dt support so booting with a device tree doesn't seem to work. Need something like for example this commit that added it for panda in the 3.0 tree:

Grrrrr. One might speculate about the reasons why those tidbits are reported missing only after the freeze date. :-/
I'm traveling to Prague with Grant tomorrow, so we should be able to figure out what needs merging between two flights.

Sorry, we have had 3.1 ci packaged kernel builds going for only about a week now and the lava submission only started working a couple of days ago. Also the lava kernel testing boots without dt so the bug did not show up until I did a manual test today after the release.

Here is my workaround for now. I brought forward the dt support from 3.0.
git://git.linaro.org/ubuntu/linux-linaro-precise.git 001947f dt: Linux dt usage model documentation b5f9d90 arm/dt: vexpress: add basic DT platform matching support b2b9f46 arm/dt: Add basic devicetree support to IGEPv2 and v3 84afe31 arm/dt: Add a make rule to build dtb for enabled boards f4575a6 arm/dt: Add basic device tree support for Beagleboard 2f332b62 arm/dt: Add basic device tree support for mx51 and mx53 boards 2e19aec arm/dt: Add basic device tree support for overo 41a788d arm/dt: Add basic device tree support for smdkv310 board 13d38b1 arm/dt: Add Pandaboard devicetree support
I left out the tegra and irq stuff. This works for panda I have not tested any other platforms yet.

Looks like the Origen board support missed something here. I'm getting:

Yes, removing that line is a good fix. With a relatively recent u-Boot (i.e. not older than a few years) then this line is redundant.

Or if you prefer the ultimate fix:

or grab latest linux-linaro-3.1 (I won't tag it just yet in case other small things turn up).
