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.

Before I tried the above, I was able to get a sysrq-t of the hang:
