Comment 11 for bug 1587089

It looks like kernel from trusty-proposed doesn't solve neither this problem nor https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1587087 (if set ~100 MB, kernel doesn't panic, but system "freezes"). What kind of information can help you? Is it right kernel?
