I just mentioned that because I've seen 8K stacks help in certain situations.  8K stacks are still the default configuration option in the vanilla kernel.  Some distributions (CentOS / Fedora) have switched to 4K by default because they help with memory consumption in highly threaded environments like web servers.

In this case, it looks like his kernel is compiled with the softlockup 
detector code and it is falsely triggering.  Disabling that should 
remove the warning message at the very least.
