That is -mm1, I've already looked at both... the patches listed below are 
minor fixes / improvements...

The name of the 2.6.11-rc1-mm2 patch which probably fixed your issue is:

uml-fix-a-stack-corruption-crash.patch

If it's not a problem, try removing it from -mm2 and recompiling, and test if 
you get the crash with the new kernel (which is what I expect)...
