Steven, what's your plan with this patchset please? 

It has been tested by Petr here on the systems under the loads that are 
able to trigger the hangs.

It'd be nice to have this in 3.17, so that we can then start working on 
fixing all the remaining printk() calls in NMI context once this biggest 
offender (stack dumping) is done.

Thanks,
