Wysocki" Cc: Linux Kernel Mailing List , Kernel Testers List , Maciej Rutecki , Florian Mickler , Bart Van Assche , Neil Brown , Jens Axboe Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 8BIT Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1396 Lines: 35 Is this machine running a RAID5 setup or something like that? There is a known interaction with the new block layer plugging code and MD. The "hung task" report in that bugzilla looks very much like that issue. And you do have "root=/dev/md0", so clearly there's some md thing going on. And bisecting might not work all that well for it, because I suspect it ends up being very much a matter of IO patterns how it triggers. Neil supposedly has a patch for it, but I haven't seen it yet.
