Can you please retest with latest -nightly? Also does the test complete after 30minutes or just time out? The loops are way too big in these tests. I think they only need to write say a couple of pages worth of data, rather than the megabytes they do now. commit f00efff326610fdba92dbc91d951790a3320052e Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Mon May 19 08:44:12 2014 -0700 store_dw_loop: make loops smaller commit 3005ac3ee8d7aede73a3e63d2068a6074156ebe5 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon May 19 18:11:34 2014 +0200 Revert "store_dw_loop: make loops smaller" Temporary revert until we have the test results. Needs to be re-reverted again after QA has run a test round and timed the tests again.
