Comment 109 for bug 1569925

I'm verifying for trusty and its taking sometime because looks like system still hangs on shutdown. I have generated a kdump (from a watchdog timer) in the exact moment trusty is hanging on shutdown to see why BUT crash can't handle a kdump from this new kernel and I still don't know why. Testing latest crash tool to see if its because of recent meltdown/spectre patches or something like it.
