Seems to be somewhat racy - had one attempt that obviously got into some grand
Mongolian flustercluck, because I had a 2M printk buffer defined, and more
than 2M worth of apparently looping output saying that the netconsole/printk
path was poisoning.  I defined the printk buffer to 4M, added a initcall_debug,
and then it managed to die in a reasonable amount of time.  Here's the whole
thing from when it starts blurbing out the POISONS messages until it
rolls over and dies (about 736 lines).

(Interestingly, I can't find any of the 3 addresses listed in the 'list_add
corruption' message anywhere *else* in the netconsole output, and the last thing
we hear from before the kersplat is apparently an RCU callback in a softirq?)
