I will try it then, but it isn't very reproducible :(
But my system hung after some list corruption warnings... I hit the
corruption 4 times...
So, Dozens of corruption warnings followed after this one:

And after I reboot my system, trying to recover building my kernel,
the system hung again, and I got following warnings:

So is it possible that my previous BUG is triggered by slab list corruption?
