Yes, probably, but it was just a suggestion, because DDB said that it 
needs KDB to compile :) but INVARIANTS just stopped compiling with an 
error so I couldnt guess what was the problem. The error could be more 
informative maybe?

Just a cosmetic thing though. Nothing vital. But I guess there is a real 
problem about this panic: sorele when the kernel is compiled with SMP 
support. If this happens again and I cant get a kernel dump or 
something, I will compile my kernel without SMP... since I dont even 
have multiple processors, I was just testing hyperthreading...
