The config file is here: http://people.linaro.org/~michaelh/incoming/precise.config It's mainly turning power management and similar features off. I didn't touch the errata or other core config. The next step would be to run the Ubuntu supplied build and see if performs the same as my reconfigured version to check if it's in the Precise tree or just my fault. -- Michael _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
