The few last before the list corruption BUG (you have to have LIST_DEBUG > enabled) -- but it seems you never reached that phase? 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?)
