Tried this, kernel would not boot up any further when I had that enabled alongside the 'extra' debugging options in the kernel:

My netconsole is not working right at the moment either so I was not able to pull a sysrq-of this, but it hung twice, once on one device, rebooted then it hung on another device the second time.
