After tried with SMP with different combination of
debug.mpsafe{net,vm,vfs}, UP kernel, all the same.

Also, I did tune

options         MAXDSIZ=(2048UL*1024*1024)
options         MAXSSIZ=(128UL*1024*1024)
options         DFLDSIZ=(2048UL*1024*1024)

in my kernel. Dont know if this afftects or not. I will try remove
them, and test again.
