Message-Id: <201306170039.GEG18281.MQFtOOSJFOLHVF@I-love.SAKURA.ne.jp>

Subject: [linux-next-20130607] rcu warning, sleep in atomic, unchecked dma alloc, bad address access
I get below failures using 3.10.0-rc4-next-20130607.
Let me know whether these are already reported/bisected or not.
Trace 3 is known since linux-next-20121127, and still waiting for patches from
Don Fry.
Config is at http://I-love.SAKURA.ne.jp/tmp/config-3.10-rc4-next-20130607 .
Full log is at http://I-love.SAKURA.ne.jp/tmp/dmesg-3.10-rc4-next-20120607.txt .
Trace 5 is a trace with TOMOYO 1.8 patch applied (though TOMOYO 1.8 should be
unrelated).
Regards.
