the result is:

| 870d6656126add8e383645732b03df2b7ccd4f94 is first bad commit | commit 870d6656126add8e383645732b03df2b7ccd4f94 | Author: Tejun Heo <tj@kernel.org> | Date: Mon Aug 25 19:47:25 2008 +0900 | | block: implement CONFIG_DEBUG_BLOCK_EXT_DEVT
and meanwhile 2 other test-systems failed to boot as well - both have CONFIG_DEBUG_BLOCK_EXT_DEVT=y.
So i guess this debug feature is working as expected.
I guess we should mark CONFIG_DEBUG_BLOCK_EXT_DEVT=y as really dangerous to enable because contemporary distributions (i tried Fedora 9) fail with it too?
